4-Year Evangelist Cycle
Ethiopian years follow a 4-year cycle named after the four Evangelists:
• John (ዮሐንስ) - Leap Year (Pagume has 6 days)
• Matthew (ማቴዎስ) - Standard Year
• Mark (ማርቆስ) - Standard Year
• Luke (ሉቃስ) - Standard Year
How Ethiopian-to-Gregorian conversion works
The Ethiopian calendar has 13 months: twelve months of exactly 30 days, followed by Pagume, a short month of 5 days (6 in a leap year). The year starts on Meskerem 1, which falls on 11 September in the Gregorian calendar, or 12 September in the year before a Gregorian leap year. Ethiopian years run about 7 years behind the Gregorian year from September to December and about 8 years behind from January to August.
DateSync converts every date through its Julian Day Number, a continuous day count that both calendars map onto. This avoids the 1–2 day errors that come from adding or subtracting a fixed offset, and it stays correct for every year, not just 1900–2099.
Leap-year rules
An Ethiopian year is a leap year when the year number leaves a remainder of 3 after dividing by 4 (for example 2015 and 2019). In a leap year, Pagume has 6 days. The Gregorian calendar adds a leap day when the year is divisible by 4, except century years not divisible by 400.
Supported input
Enter one date per line as day/month/year, month/day/year or year-month-day. Dates are checked against real month lengths, so 6 Pagume in a non-leap year is rejected instead of silently converted.
Frequently asked questions
Why does the Ethiopian New Year change between 11 and 12 September?
The Ethiopian leap day is added at the end of the year before a Gregorian leap year, pushing the next New Year to 12 September.
Is the conversion exact?
Yes. Dates are converted by Julian Day Number and validated against real month lengths for each calendar.
How many dates can I convert at once?
Paste as many lines as you like; processing happens in your browser and nothing is uploaded.
The result shows the Ethiopian date in Latin and Amharic month names, the date written in Ge’ez numerals, the weekday in Amharic and English, whether the Ethiopian year is a leap year, the day of the Gregorian year, and the Julian Day Number used for the calculation.
Ge’ez numerals
Ge’ez numerals have no zero and use separate symbols for units, tens, and hundreds. 2019 is written ፳፻፲፱: twenty hundreds (፳፻) plus ten (፲) and nine (፱).
Hijri dates
The Hijri date is calculated with the tabular civil Islamic calendar. Real Hijri months start with moon sighting, so a printed date can differ by one day.
Frequently asked questions
What is today’s Ethiopian date?
The strip at the top of every page shows today in the Ethiopian, Gregorian and Hijri calendars.
Why is Ethiopian time zone date sometimes different?
The Ethiopian day changes at local midnight, the same as the Gregorian day, so the two dates always change together.
Can I convert a date before 1900?
Yes, the Julian Day Number method works for any year.
DateSync counts whole months from the birth date using the anniversary method, then counts the remaining days. If a birth day does not exist in a month (31 January plus one month), the date moves to the last day of that month. People born on 29 February have their birthday on 28 February in common years.
Gregorian vs Ethiopian age
The same birth date produces a different number of months and days in the Ethiopian calendar, because Ethiopian months are always 30 days and a year has 13 months. Both versions are shown so you can use the one an office or document requires.
Hours and minutes lived
Total days come from the calendar. Hours and minutes are real elapsed time since midnight on the birth date in your device’s time zone.
Frequently asked questions
Why is my Ethiopian age different in months and days?
Ethiopian months have 30 days and there are 13 per year, so the month and day parts differ even when the years agree.
What if my birthday is 29 February?
It is observed on 28 February in common years, and the countdown follows that rule.
Is my birth date stored?
No. Everything is calculated locally in your browser.
The Ethiopian day is split into two 12-hour halves that start at about 6:00 in the Western clock, near sunrise and sunset. To convert, subtract 6 hours from the Western time (or add 6, the result is the same on a 12-hour dial). So 7:00 AM is 1:00 in Ethiopian time, 12:00 noon is 6:00, and 6:00 PM is 12:00.
Periods of the day
Ethiopian hours are followed by a period word such as morning (ጠዋት), afternoon, evening or night (ሌሊት), so “1:00 in the morning” always means 7:00 AM.
Why it matters
Appointments in Ethiopia are often given in Ethiopian time. Always confirm which system is meant when scheduling with someone abroad.
Frequently asked questions
What is 8:00 AM in Ethiopian time?
2:00 in the morning (ጠዋት 2:00).
Does the Ethiopian date change at 6:00?
No. The calendar date changes at midnight; only the hour numbering restarts at 6:00.
Every country is mapped to an IANA time zone from your browser’s own time-zone database, so daylight-saving changes are applied for the exact date you choose. A custom date and time is read in the source country’s zone, converted to a universal instant, and then shown in every target zone.
Day differences
Because zones range from UTC−12 to UTC+14, the date can differ by a day. Each card says whether it is the same, next or previous day compared to the source.
Multi-zone countries
Countries with several zones, such as the United States, Russia, Brazil and Australia, use their capital or main zone. Select a city from the full zone list for other regions. Ethiopia uses UTC+3 all year and has no daylight saving.
Frequently asked questions
Does it handle daylight saving time?
Yes, offsets are calculated for the exact date and time you select.
How do I plan a meeting across countries?
Set the source to your country and the time you propose, then read each target’s local time and day.
Why do two countries share the same hour but different dates?
Zones far apart across the date line can be on different calendar days at the same moment.
Each participant has working hours (9:00–17:00 by default). The planner checks every 30-minute start time of the first participant’s day against every participant’s local clock for the whole length of the meeting. A time is Ideal when everyone is inside working hours, and Acceptable when someone is up to two hours before or after their normal day. Times that fall at night for anyone are excluded.
Daylight saving and date lines
Local times come from the IANA time-zone database in your browser, so daylight-saving changes are applied for the exact meeting date. Each person’s time shows a (+1 day) or (−1 day) note when their calendar date differs from the reference participant’s.
Sharing the result
Copy a ready-to-send invite that lists the local time for each participant, or download an .ics file that opens in Google Calendar, Outlook and Apple Calendar.
Frequently asked questions
What are the default working hours?
9:00 to 17:00 local time, which you can change for each person.
Does it handle daylight saving time?
Yes, offsets are calculated for the exact date you choose.
The map computes the sun’s position directly in your browser from the date and time: the point on Earth where the sun is directly overhead, and the curve (the terminator) that separates day from night. The shaded side is night. No map tiles or tracking services are used.
Reading the markers
Countries from your World Time list appear as dots with their local time. A dot is amber in daytime, orange in twilight (the sun is less than 6° below the horizon) and indigo at night. Click “Live now” to return to the current moment, or drag the time slider to preview any hour of the day.
Why the line moves through the year
Earth’s axis is tilted about 23.4°, so in northern summer the night side reaches further south and in northern winter it reaches further north. At the equinoxes the terminator runs almost pole to pole.
Frequently asked questions
Is the map live?
Yes. It updates every 15 seconds while you are on this page, or you can scrub to any time.
Which time does the slider use?
Universal Time (UTC). Local times appear on each marker.
How accurate is the day and night line?
It uses standard astronomical formulas and is accurate to a fraction of a degree, which is well under a pixel on this map.
Every calendar day from the start date to the end date is checked. Days that fall on a weekend you selected are skipped, and so are any holiday dates you list. Everything else counts as a working day. Tick “include end date” when both the first and last day should be counted.
Custom weekends
Many countries do not use Saturday and Sunday as the weekend. Choose any combination of days, for example Friday and Saturday, or only Sunday.
Adding working days
Enter a start date and a number of working days (negative to go back) to get the resulting date, skipping weekends and holidays. This is useful for delivery estimates, notice periods and deadlines.
Frequently asked questions
Are public holidays excluded automatically?
No. Paste the holiday dates you want to exclude, one per line in YYYY-MM-DD form.
Can I change the weekend?
Yes, tick any days of the week as the weekend.
Does it calculate hours?
Yes, working days are multiplied by the hours per day you set.
A Unix timestamp counts the seconds since 1 January 1970 at 00:00:00 UTC. Many systems use milliseconds (13 digits), microseconds or nanoseconds instead. The converter detects the unit from the size of the number.
Date to timestamp
Type an ISO 8601 date such as 2026-11-08T12:00:00Z, or any date your browser can read, to get seconds and milliseconds. Include a Z or an offset such as +03:00 so the time zone is clear.
Batch conversion
Paste one timestamp per line to convert a whole log. Each result is shown in UTC ISO format. Nothing is uploaded.
Frequently asked questions
How do I tell seconds from milliseconds?
Ten-digit values are seconds and thirteen-digit values are milliseconds. The tool detects this automatically.
Does a timestamp have a time zone?
No. It always refers to UTC. Local time is only a way of displaying it.
What happens in 2038?
Systems storing seconds in 32 bits overflow in January 2038. This tool uses 64-bit numbers and is not affected.
Each bar shows the share of the period that has passed on your device clock, with the days left. The Ethiopian year bar runs from Meskerem 1 to the end of Pagume.
ISO weeks
ISO 8601 weeks start on Monday, and week 1 is the week that contains the first Thursday of the year. Because of this the first days of January can belong to week 52 or 53 of the previous year.
Frequently asked questions
Why is my ISO week different from my calendar?
Some calendars start weeks on Sunday or number them differently. ISO weeks always start on Monday.
Your title, the exact moment and the time zone are encoded into the part of the link after the # sign. That part is never sent to a server, so the event stays private. When someone opens the link, their browser converts the moment into their own time zone.
Sharing
Copy the link into a chat or email, or download an .ics file to add the event to a calendar.
Frequently asked questions
Is my event stored anywhere?
No. It lives only inside the link.
Do viewers need an account?
No, they just open the link.
Which time zone should I choose?
The zone you used when typing the date and time. It handles daylight saving for that date.
Press Start to begin timing and Lap to record split times. The display shows minutes, seconds and milliseconds and uses the browser’s high-resolution clock.
Countdown timers
Add as many timers as you need, each with its own label. When a timer reaches zero it shows a message and plays a short beep generated in your browser. Keep this tab open so the browser does not pause it.
Frequently asked questions
Does the timer keep running in the background?
Browsers may slow background tabs, but timers are based on the clock, so they finish on time.
The calculator uses standard astronomical formulas for the sun’s declination and the equation of time, then solves for the hour angle at each sun height. Sunrise and sunset use −0.833° to account for the sun’s radius and atmospheric refraction.
Twilight
Civil twilight ends when the sun is 6° below the horizon, nautical at 12° and astronomical at 18°. Golden hour is the period when the sun is within 6° above the horizon.
Polar regions
Near the poles the sun can stay above or below the horizon for days, and the tool reports polar day or polar night instead of times.
Frequently asked questions
How accurate are the times?
Typically within a minute or two for most places.
Which time zone is used?
The country’s main zone, or your device zone when you use your location.
New and full moon times are calculated with the main terms of Jean Meeus’s lunar phase algorithm, accurate to a few minutes. Illumination and age are derived from how far the moon is between two new moons.
The monthly calendar
Each day shows the phase at midday UTC. New and full moon days are highlighted. Hover a day for its illumination.
Frequently asked questions
Why does the full moon date differ by place?
Because the moment of full moon is the same worldwide but the local date depends on your time zone.
Is the Ethiopian Church calendar based on the moon?
Fasika and other movable dates use a Julian-based calculation, not the real moon.
National holidays such as Enkutatash (1 Meskerem), Meskel (17 Meskerem), Adwa Victory Day (23 Yekatit), Labor Day (23 Miyazya), Patriots’ Victory Day (27 Miyazya) and the Downfall of the Derg (20 Ginbot) fall on fixed Ethiopian dates. Genna (7 January) and Timkat (19 January) are tied to the Julian calendar, so their Ethiopian date can differ by a day between years.
Fasika (Easter) is calculated with the Julian-based Alexandrian method used by the Ethiopian Orthodox Tewahedo Church, so it often differs from Western Easter. Good Friday (Siklet), Hosanna and Great Lent move with it.
The main fasts
Abiy Tsom (Great Lent) lasts 55 days before Easter. The Apostles’ Fast begins the Monday after Pentecost and ends on 5 Hamle. Filseta runs 1–16 Nehase, and the Fast of the Prophets (Tsome Nebiyat) begins on 15 Hidar. Gahad fasts fall the day before Genna and Timkat.
Customise
You can edit, add or delete entries and export the year to a calendar file. Islamic holidays are not included because their dates depend on moon sighting.
Frequently asked questions
When is Ethiopian Christmas?
Genna is 7 January in the Gregorian calendar.
Why does Easter differ from Western Easter?
The Ethiopian Church uses the Julian-based Alexandrian calculation, so the date often differs.
Adding one month to 31 January gives 29 February in a leap year (28 otherwise), not a date in March. The result is clamped to the last day of the target month, and the tool tells you when it did so.
Gregorian or Ethiopian months
Choose which calendar counts the months and years. With Ethiopian months a year is 13 months, so “add 1 year” moves by 13 Ethiopian months.
Duration between dates
The duration card gives years, months and days in both calendars, total days, weeks and Monday–Friday days. Tick “include end date” when both days should count, as in many contracts.
Frequently asked questions
How many weekdays are between two dates?
The duration card counts Monday–Friday days, excluding public holidays.
Does it handle leap years?
Yes, both Gregorian and Ethiopian leap rules are applied.
Should I include the end date?
Include it when both the first and last day count, for example a rental from the 1st to the 5th is 5 days.
Open Excel, press Alt+F11, choose Insert › Module, paste the code, then save the workbook as .xlsm. Use =EthiopianToGregorian(day, month, year) and =GregorianToEthiopian(date) in cells.
Accuracy and limits
The functions validate month and day lengths, including Pagume, and return #VALUE! for impossible dates. They are exact for Gregorian dates from 1901 to 2099, the range of Excel dates and of the fixed 11/12 September rule. Use the online converter for other years.
Macro security
Macros only run in .xlsm files and when you allow them. Review any code before running it.
Frequently asked questions
Why do I get #VALUE!?
The date is impossible, for example Pagume 6 in a non-leap Ethiopian year.
Does it work on Mac?
Yes, VBA works in Excel for Mac, although the editor shortcut differs.
Can I convert a whole column?
Yes, fill the formula down or use the Batch Converter.
The Ethiopian calendar counts from a different calculation of the Annunciation and Incarnation (Amete Mihret) than the Western one, giving a gap of 7 years from September to December and 8 years for the rest of the year.
Months and Pagume
The months are Meskerem, Tikimt, Hidar, Tahsas, Ter, Yekatit, Megabit, Miyazya, Ginbot, Sene, Hamle and Nehase, each with 30 days, followed by Pagume with 5 days or 6 in a leap year.
Evangelist cycle
Years rotate through the four Evangelists: John (leap), Matthew, Mark and Luke. The year of John has the sixth day of Pagume.
Use the Ge’ez numeral studio
Below, convert any number into Ge’ez numerals and browse the month, numeral and cycle tables.
Frequently asked questions
How many months does the Ethiopian calendar have?
Thirteen: twelve of 30 days and Pagume of 5 or 6 days.
When is the Ethiopian New Year?
Usually 11 September, and 12 September in the year before a Gregorian leap year.
