Calendar converter について
A date on a Saudi contract, an Iranian birth certificate, a Japanese pension letter or a Nepali citizenship card is written in a calendar of its own. This converter takes a day in any one of thirteen calendars and shows it in all the others at once: Gregorian, Japanese era, Islamic Hijri, Persian Solar Hijri, Thai Buddhist Era, Minguo (Taiwan), Chinese lunar, Korean lunar, Nepali Bikram Sambat, Ethiopian, Hebrew, Indian national (Saka) and Coptic.
Conversions work in both directions. Pick the calendar you have, enter its year, month and day, and the Gregorian date and every other calendar update together, each with the weekday and the date as it is written locally, in Arabic, Persian, Thai, Japanese, Chinese, Korean, Hebrew, Devanagari or Ge'ez script. Months exist only where they really do, so Adar I appears only in Hebrew leap years and a Chinese leap month only in the year that has one.
The Islamic, Persian, Hebrew, Ethiopian, Coptic and Indian calendars come from the calendar data built into your browser. Chinese and Korean lunar dates are read from the Hong Kong Observatory and Korea Astronomy and Space Science Institute tables, and Bikram Sambat from a month-length table compared with seven open-source libraries and the calendar published by Hamro Patro.
What it cannot know is a local decision. An Islamic month that starts with a moon sighting can begin a day earlier or later than any printed calendar, and Bikram Sambat years after 2083 BS are projections until Nepal publishes them. The chart below the converter lists the year numbers of the coming decade in every calendar.
プライバシー
Every conversion is worked out by the page in your browser; no date you enter is sent anywhere. The chosen calendar, date and Islamic calendar type are remembered in this browser's local storage and in the page address, so a copied link opens the same day.
