About Safar
Safar (صَفَر) is the second month of the Hijri calendar. Its name means “Empty / void.” The second month. Its name is often linked to houses left empty when people travelled after the sacred months.
Like every Hijri month it has 29 or 30 days, determined in the Umm al-Qura calendar by the official tables and in the tabular calendar by a fixed arithmetic rule. Because the lunar month depends on the sighting of the new crescent, the exact first day can differ by a day from the calculated date.
