Note that arithmetic dates may differ by a day from the local moon-sighting calendar.Public holidays calendarEvery public holiday in 26 countries, for any year, computed from the rules rather than copied from a list: Easter and the eleven feasts that follow it, the nth-Monday holidays, the British substitute days and the Colombian Emiliani shift. Regional days included for Germany, Spain, France, the UK and Portugal.School holidays calendarSchool holiday dates for France, Germany, Switzerland, Austria, Belgium, Luxembourg and Portugal, imported from the authorities that decree them — with the French academy picker that answers which zone you are in. Unlike public holidays these dates follow no rule, so the page shows when the snapshot was taken and how far it reaches, and names the countries where no single source exists.Day of Year CalendarA full year on one page: twelve month blocks where every cell carries its day-of-year number from 1 to 365 or 366, today highlighted, and each date's ISO week, quarter and days remaining one click away.Birthday across cultures calculatorThe same birth date gives three different ages: the Western count of completed birthdays, the Chinese 虚岁 (one at birth, +1 each Lunar New Year, using a 1900–2100 table), and the Korean traditional age. It also gives your Chinese and Western zodiac signs.Flight distance calculatorThe distance between two airports as the crow flies — the great-circle distance from the haversine formula — plus a realistic flight distance with a routing allowance and an estimated flight time from the aircraft's cruising speed. Enter IATA codes (JFK, CDG…), city names, or coordinates.Julian Date converterConvert a calendar date and time to the astronomical Julian Date (JD) and back, live. It also returns the Modified Julian Date (MJD = JD − 2400000.5) and the Unix timestamp, and lets you pick the Gregorian or Julian calendar for dates before the 1582 reform. Astronomer-grade: noon UTC on 1 January 2000 comes out to exactly JD 2451545.0.

Frequently asked questions

What is Chinese lunar calendar converter?

Convert dates between the Gregorian solar calendar and the traditional Chinese lunisolar calendar (1900–2100), both ways and live. It shows the lunar month and day names, the sexagenary stem-branch (干支) year and its zodiac animal, and correctly handles leap months (闰月). Find out which lunar date a birthday falls on, or when Chinese New Year lands.

When would I actually use this?

Answering a scheduling question exactly: how many working days until a deadline, what date falls sixty days out, and what time that is for a colleague elsewhere.

What is the most common mistake?

Counting days by subtracting dates and forgetting whether the endpoints are included. Inclusive and exclusive counts differ by one, which is the difference between meeting a deadline and missing it.

How is Chinese lunar calendar converter different from Hebrew calendar converter?

They sit next to each other but answer different questions: Hebrew calendar converter is the one to open when you need it to convert any date between the Gregorian and Hebrew (Jewish) calendars, both ways and live as you type. It shows the Hebrew day, month name (Tishrei, Cheshvan, Av…) and year counted from Creation (Anno Mundi), correctly handling leap years where Adar splits into Adar I and Adar II. Powered by the exact Dershowitz–Reingold arithmetic algorithm. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Hijri calendar converter is the closest one after this: Convert dates between the Gregorian and Islamic (Hijri) calendars in both directions, updating live as you type. It shows the Hijri day, month name (Muharram, Safar, Ramadan…) and the year counted from the Hijra (AH), using the tabular civil algorithm with the standard astronomical epoch. Note that arithmetic dates may differ by a day from the local moon-sighting calendar.

What else is worth having open alongside it?

Public holidays calendar and School holidays calendar — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Calendar arithmetic follows the proleptic Gregorian calendar and the IANA time-zone database, so daylight-saving transitions and leap years are handled. Public holidays vary by country and region and are not assumed.
