What is The Creator's Calendar?
A lunisolar calendar: real lunar months kept in the seasons of the solar year — the calendar of the Arabs in the Prophet's era.
- Its months stay in their seasons thanks to Al-Nasi, a thirteenth month: the two Rabi' months in spring and Ramadan in autumn — while the Lunar Hijri calendar drifts through the seasons.
- The day begins at dawn, and the month begins with the new moon by the conjunction and the moon's age.
- History agrees with it: the Hijra on Monday 12 Rabi' al-Awwal, Badr on Friday 17 Ramadan, and the Prophet's death on Monday 12 Rabi' al-Awwal — weekdays that match The Creator's Calendar, not the Lunar Hijri calendar.
