Safar (صفر) is a word that means “empty.” This corresponds to a time where people’s houses were empty. It also means "whistling of the wind". When this name was assigned to this month, it was probably a windy time of the year. Most of the Islamic months were named according to weather conditions at the time. However, since they are based on the moon, the months shift about 11 days every year. So, the seasons do not necessarily correspond to the name of the month anymore.
The Islamic calendar is a lunar calendar, and months begin when the first crescent of a new moon is sighted. Since the Islamic lunar calendar year is 11 to 12 days shorter than the solar year, Safar migrates throughout the seasons. The estimated start and end dates for Safar are as follows (based on the Umm al-Qura calendar of Saudi Arabia):
