The well-known Al-Ujairi Hijri calendar, which appeared at the beginning of the last century, relied on scheduling the months without relying on astronomical calculations. This calendar is considered one of the most accurate and best civil calendars through which events are documented without the use of uncontrolled observational calendars.
This program also contains the Umm Al-Qura Calendar, third edition, which was approved by Dr. Saleh Al-Ujairi later began using astronomical calculations to reset the calendar. Through the application, you can compare the authentic Al-Ujairi calendar with the Umm Al-Qura calendar, the third version, which is approved today in Saudi Arabia.
The original Ujairi calendar is still used in many programs, including Microsoft programs. The program helps you convert between the Ujairi calendar and the Umm al-Qura calendar and any other calendar, including the Gregorian calendar.
