About this tool
Convert any date between the Gregorian, Persian (Solar Hijri), Islamic (Hijri), Hebrew, and a dozen other calendar systems at once. Pick a date in any supported calendar and instantly see it in all the others, along with the weekday, day of the year, and leap-year status. You can also step the date forward or backward by days, months, or years within your chosen calendar. Everything runs locally in your browser using the built-in Intl calendar data — no data leaves your device.
