Safar is the second month in the Hijri Calendar. Normally, a Hijri day starts at sunset. Thus, observing the crescent of a new Hijri month occurs during the sunset.
Like all the other Hijri lunar months, the month of Safar spans over 29 or 30 days; and for that reason, we conduct the lunar astronomical observations and calculate the lunar months to know their exact dates every year.

The Hijri Calendar is a lunar dating system, and its months begin when the lunar phase called First Crescent of a new moon is sighted.
The year of the Hijri lunar calendar is 11 to 12 days shorter than the solar year. Thus, Safar and all other lunar months migrate backward throughout the seasons, during a cycle of about 33 solar years.
