First of the month

The first of the month or first day of the month is the recurring calendar date position corresponding to the day numbered 1 of each month. In the Gregorian calendar (and other calendars that number days sequentially within a month), the first day occurs in every month of the year, and therefore occurs twelve times per year.

In addition to these dates, this date occurs in months of many other calendars, such as the Bengali calendar and the Hebrew calendar.
