Extract Month from Date in Excel

What this does

These three read one component out of a date serial number. MONTH returns 1–12, DAY returns 1–31, YEAR returns the four-digit year. The single most common surprise is that MONTH returns a number: to get a month NAME you need =TEXT(A2, "mmmm") for January or "mmm" for Jan, and TEXT returns text, so the result sorts alphabetically rather than chronologically. That is why a report grouped by month name usually runs April, August, December unless the sort is done on the month number and only the display uses TEXT. The second thing worth knowing is that a "month and year" grouping key should not be built by concatenating MONTH and YEAR — =TEXT(A2,"yyyy-mm") gives a key that sorts correctly, and =EOMONTH(A2,0) gives a real date you can chart on a time axis. Finally, these functions need a genuine date: fed text like "03/04/2026" they return #VALUE!, which is the fastest way to discover an imported column never became dates at all. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “extract month from date in excel”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the tool above before you touch the real workbook. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. The point is a workflow that saves repeating the same clicks every week, but the practical win is that someone else can open the file and understand what happened without asking you.

A worked example

A2 holds 2026-08-14. =MONTH(A2) → 8, =YEAR(A2) → 2026, =DAY(A2) → 14. For a label rather than a number, =TEXT(A2,"mmmm") → August. For a grouping key that sorts properly, =TEXT(A2,"yyyy-mm") → 2026-08. To collapse a whole column to month starts for a PivotTable or chart, =EOMONTH(A2,-1)+1 → 2026-08-01. Almost every monthly report starts by splitting a date column into parts, and the two traps — numbers rather than names, and text keys that sort alphabetically — account for most of the wrong-looking summaries that follow. One habit worth forming early: name the cells that hold your inputs, so the formula reads in plain language instead of a string of cell addresses. A reviewer — or you in three months — can then follow the logic without decoding what B7 and D2 were supposed to mean, which is most of what makes a sheet maintainable.

In Google Sheets

Google Sheets handles this almost identically to Excel. The formula syntax above is the same, and the menu lives under a slightly different label rather than a ribbon tab. Use the platform toggle at the top of the page to switch every keyboard shortcut between Windows and Mac, and expect at most cosmetic differences in naming. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. Treat “extract month from date in excel” as a small building block rather than a chore. Once the inputs sit in their own cells and the formula reads from them, the same setup answers a dozen related questions with a tweak, and Excel keeps every dependent figure current as the data changes. The tool above is there so you can rehearse and verify before committing anything to a real workbook; the steps and worked example are there so the logic sticks. Get it right once and it stops costing you time — it starts saving it, every time the question comes back around.

Common mistakes

• Expecting MONTH to return "August" — it returns 8, and the name needs TEXT.
• Sorting or grouping on a TEXT month name, which orders April, August, December instead of chronologically.
• Building a month-year key as MONTH&YEAR, which makes 12026 for December and sorts nonsensically.
• Running these against text that merely looks like a date and reading #VALUE! as a formula problem rather than a data problem.
• Using =YEAR(TODAY())-YEAR(B2) as an age, which is wrong by up to a year — DATEDIF with "y" is the correct tool.
