The Year of the Islamic Calendar

Umar said no we will have our own calendar so which year should we begin with? So the Sahaba differed one of them said with the death of the Prophet ﷺ but this was then say no this is not appropriate any sad time you want to mark the calendar day. Ali ibn Abi radiab said the year of the Hidra shall be the first year of the calendar. This was when the situation of the Muslims changed from dul to isa from being humiliated to being honored. Once again realize there is no zero year. There is no zero time. It is only at times of weakness where we follow everybody else and this is the reality of life.
