About this converter

  • Persian and Gregorian: conversion between these two is exact. The calculation has been checked against the official table of leap years of the Calendar Center of the Institute of Geophysics, University of Tehran, for the years 1206 to 1498.
  • Islamic: dates follow Iran's official calendar, which starts each month with the sighting of the new crescent. For months not yet announced, the date is an astronomical estimate and may move by a day. Other countries' Islamic dates sometimes differ by a day.
  • Imperial: the same day and month as the Persian date, with the year 1180 higher.
