Step by step
- 1Enter your date in A2.
- 2In a result cell, enter =DATE(YEAR(A2),MONTH(A2),1).
- 3This reconstructs the date using the same year and month, but always with day 1.
- 4Format the result cell as a date.
- 5Alternatively, use EOMONTH to get the first day of the next month: =EOMONTH(A2,-1)+1.
Tips
- =EOMONTH(A2,-1)+1 is a concise alternative: EOMONTH with -1 returns the last day of the previous month, and adding 1 gives the first day of the current month.
