The Hijri calendar is based on the lunar cycle to determine the months.
Some Arab countries, such as Saudi Arabia, take it as the official calendar of the state. It was established by Caliph Omar Ibn Al-Khattab. The Hijri calendar differs in the number of days from the Gregorian calendar year, with 11 less days than the Gregorian year.
Hijri calender months are either 29 days or 30 days while Gregorian months are either 30 days or 31 days.
Ramadan is one of the months that is of great value to Muslims, so everyone is interested in finding the date of Ramadan so that they can prepare for it.
Fasting in the month of Ramadan is considered one of the pillars of Islam, during which Muslims abstain from food and drink until the time of the Maghrib call to prayer, in addition to a number of prohibitions that Muslims must avoid so as not to invalidate the fast.
