Convert a date into its calendar quarter (1–4).
Copy this formula
=ROUNDUP(MONTH(A2)/3, 0)MONTH returns 1–12; dividing by 3 and rounding up groups months into quarters (Jan–Mar → 1, Apr–Jun → 2, and so on). Concatenate with "Q" for a label like Q2.
="Q"&ROUNDUP(MONTH(A2)/3, 0)→Q2April falls in Q2.
=ROUNDUP(MONTH(DATE(2026,11,15))/3, 0)→4November is in the fourth quarter.
=INT((MONTH(A2)+2)/3)→3An equivalent formula; a date in August returns 3.
=YEAR(A2)&"-Q"&ROUNDUP(MONTH(A2)/3,0).
Shift the month first: =ROUNDUP(MONTH(EDATE(A2, -3))/3, 0). April to June then returns 1.
Use =DATE(YEAR(A2), 3*ROUNDUP(MONTH(A2)/3, 0)-2, 1).
An empty cell is treated as date 0, which Excel reads as January 1900. Guard it: =IF(A2="", "", ROUNDUP(MONTH(A2)/3, 0)).
