Timepath
Convert dates between the Gregorian, Julian, Hebrew, Islamic, Persian, Mayan, and a dozen other calendar systems. Understand why they differ. Explore how humans have measured time across history.
Get early accessBritain skipped 11 days in 1752. Easter moves every year by a formula unchanged since 325 AD. The Ethiopian new year falls in September. Timepath untangles all of it.
01
Enter any date in any supported calendar and see it across all the others simultaneously. "March 14, 2024" in Gregorian reads as 4 Adar II 5784 in Hebrew, 4 Ramadan 1445 in Islamic, 24 Esfand 1402 in Persian — all at once.
02
Understand the rules behind the conversions — lunar cycles, leap year calculations, intercalary months, and the political decisions that reformed whole systems overnight.
03
Trace when countries adopted standard time, when daylight saving was introduced, and how UTC offsets have shifted over decades — critical for any historical timestamp.
Useful to anyone who has stared at a historical date and wondered what it actually means.
Cross-reference dates in primary sources that use different calendar systems. An Ottoman firman dated "15 Muharram 1180 AH" deserves a real answer, not a back-of-envelope guess.
Parish records in England, Jewish community registers in Poland, Ottoman tax rolls — each in its own calendar. Timepath resolves them to a common timeline so you can see the actual sequence of events.
Historical fiction demands precision. Know what day of the week the battle fell on, whether the moon was full, and how your characters would have named and written that date.
If you've ever wondered why Ramadan starts at a different time each year, why the Julian calendar drifted, or how the Mayan long count works — this is built for exactly that question.
