In Excel: use =MONTH(A2), =YEAR(A2) and =DAY(A2) to pull the three parts out of a date — each returns a NUMBER, so January is 1, not "Jan".

serial_number | required | The date to read the part from — a cell holding a real date, not text that looks like one. |
Related functions
Confirm the column really holds dates — right-aligned by default, and =ISNUMBER(A2) returns TRUE.
Use =MONTH(A2), =YEAR(A2) or =DAY(A2) for the numeric part.
For a name rather than a number, use =TEXT(A2,"mmmm") or "mmm"; remember the result is text.
For a sortable month-and-year key, use =TEXT(A2,"yyyy-mm") rather than joining two numbers.
For grouping in a PivotTable or on a chart axis, =EOMONTH(A2,-1)+1 gives a real date at the month start.
If you get #VALUE!, the cell is text: fix it with DATEVALUE or Data ▸ Text to Columns before extracting anything.
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 “convert mm/dd/yyyy to month and year 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 data step that keeps your analysis trustworthy, 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
If you are in Google Sheets rather than Excel, the good news is that the formula shown here is identical and the workflow barely changes — menus sit across the top instead of in a ribbon, and a few function names differ slightly, but anything you build here moves across with little or no rework. 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 and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. Here is the takeaway for “convert mm/dd/yyyy to month and year in excel”: copy the answer if you are busy, but if you have a spare few minutes, rebuild the example in Excel yourself with the tool above open beside it. That single pass — type it, run it, watch the result move when you change an input — is what turns a formula you found into a technique you trust. Keep your inputs labelled and referenced, never hard-coded, and the same sheet stays correct and auditable as it grows. Done that way, you will not need to look this up again, and you will be the person others ask.
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 —DATEDIFwith "y" is the correct tool.
Frequently asked questions
How do I get the month from a date in Excel?
=MONTH(A2) returns the month number, 1 to 12. For the name, use =TEXT(A2,"mmmm") or "mmm".
How do I extract the year from a date?
=YEAR(A2) returns the four-digit year as a number.
How do I get month and year together?
=TEXT(A2,"yyyy-mm") gives a key that sorts correctly, and =EOMONTH(A2,-1)+1 gives a real date at the start of the month for charts and PivotTables.
How do I turn a month number into a month name?
=TEXT(DATE(2026, A2, 1), "mmmm") — build any date in that month and format it. The result is text.
Why does MONTH return #VALUE!?
The cell holds text rather than a date. Check with =ISNUMBER(A2) and convert with DATEVALUE or Data ▸ Text to Columns.
