The Bahá'í or Badí calendar is followed by members of the Bahá'í Faith in their religious life.
The start of the Bahá'í year is fixed to March 21st in the Gregorian calendar. Leap years thus follow the same pattern as Gregorian leap years. The Bahá'í year 1 began in 1844, marking the start of Babism.
Months and days
The year contains 19 months of 19 days each, each of which has a Persian name representing an aspet of God:
- Bahá (Splendor)
- Jalál (Glory)
- Jamál (Beauty)
- 'Azamát (Grandeur)
- Núr (Light)
- Rahmat (Mercy)
- Kalimát (Words)
- Kamál (Perfection)
- Asmá' (Names)
- 'Izzat (Might)
- Mashiyyat (Will)
- 'Ilm (Knowledge)
- Qudrat (Power)
- Qawl (Speech)
- Masá'il (Questions)
- Sharaf (Honor)
- Sultán (Sovereignty)
- Mulk (Dominion)
- 'Alá (Loftiness)
The 19 days of each month also use the same series of names.
To round the year out to 365 (or 366) days, four (or five) epagomenal or intercalary days are inserted between Mulk and 'Alá. These days are known as Ayyám-i-Há.
