Conversion to Gregorian Dates:

To convert an Ismaili date to a Gregorian date, you can use the following steps:

  1. Identify the month: Match the Ismaili month name with the corresponding Gregorian month. Here's a rough guide:
    • Muharram = January-February
    • Safar = February-March
    • Rabi' al-Awwal = March-April
    • Rabi' al-Thani = April-May
    • Jumada al-Awwal = May-June
    • Jumada al-Thani = June-July
    • Rajab = July-August
    • Sha'ban = August-September
    • Ramadan = September-October
    • Shawwal = October-November
    • Dhu al-Qadah = November-December
    • Dhu al-Hijjah = December-January
  2. Determine the day of the month: Add the Ismaili day of the month to the corresponding Gregorian month. Since the Islamic calendar is approximately 11 days shorter than the Gregorian calendar, you may need to adjust the day of the month.
  3. Adjust for leap years: The Islamic calendar is a lunar calendar, and it does not account for leap years. However, the Gregorian calendar has a leap year every 4 years. To account for this, you can add 1 day to the Gregorian date if the Ismaili date falls on a leap year.

Example Conversion:

Ismaili date: Jumada al-Awwal 12, 1439

  1. Identify the month: Jumada al-Awwal corresponds to May-June.
  2. Determine the day of the month: Add 12 to May, which gives us May 22nd.
  3. Adjust for leap years: Since 1439 is not a leap year, we don't need to adjust the date.

Gregorian date: May 22nd, 2018
