Find Day of Week from Date in Excel

If you just need to find day of week from date in excel and move on, the boxed answer at the top is all you need. The rest of this page is for when you want to understand why it works in Excel, adapt it to a trickier version, or make it robust enough to hand to a colleague. We keep the opening short on purpose — the depth is here when you want it, not in your way when you don’t.

Exact answer

In Excel: use =WEEKDAY(date, 2) — it returns the day of the week as a number, where return_type 2 numbers Monday as 1 through Sunday as 7.

Syntax

=WEEKDAY(serial_number, [return_type])

Arguments

ArgumentDescription
serial_numberrequiredThe date to evaluate, as a cell reference, a date, or a serial number.
return_typeoptionalControls the numbering: 1 (or omitted) = Sunday(1) to Saturday(7); 2 = Monday(1) to Sunday(7); 3 = Monday(0) to Sunday(6).

What this does

WEEKDAY takes a date and returns which day of the week it falls on, as a NUMBER from 1 to 7 rather than a name. The optional return_type decides where the week starts: the default 1 runs Sunday(1) to Saturday(7), while 2 — the common ISO choice — runs Monday(1) to Sunday(7), and 3 runs Monday(0) to Sunday(6). Because it gives a number, WEEKDAY is built for logic: flagging weekends, filtering by day, or feeding an IF. If you want the day NAME instead, use TEXT(date, "dddd") rather than WEEKDAY. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “find day of week 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

Cell A2 holds the date 2026-06-03 (a Wednesday). =WEEKDAY(A2, 2) returns 3, because with return_type 2 Monday is 1, Tuesday 2 and Wednesday 3. With the default, =WEEKDAY(A2) returns 4, since Sunday is 1 there. To flag weekends regardless of locale: =IF(WEEKDAY(A2, 2) > 5, "Weekend", "Weekday"). For the day name itself, =TEXT(A2, "dddd") returns "Wednesday". WEEKDAY is the building block for any logic that depends on the day of the week — weekend flags, shift schedules and day-based filters — because a plain number is easy to compare and feed into other formulas. A practical tip before you scale it up: build it once on a small block of test data, confirm the number against the tool on this page, and only then point it at your real sheet. That one habit catches almost every mistake while it is still cheap to fix, long before a wrong figure reaches a report or a colleague.

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. The short version of “find day of week from date in excel”: the answer is at the top of this page, the tool proves it on your own numbers, and the sections above explain why it holds so the next variation does not stump you. Excel rewards people who reference cells instead of typing values and who keep inputs separate from formulas, because that is what makes a result you can audit months later. Build it once, deliberately, with the live tool as a check, and you convert a one-off lookup into a reusable skill — which is the whole point of learning the why and not just the what.

Common mistakes

  • Expecting a day name — WEEKDAY returns a number; use TEXT(date, "dddd") when you want the word.
  • Forgetting the return_type and assuming Monday is 1 — with the default, Sunday is 1 and Monday is 2, which shifts every weekend test.
  • Pointing WEEKDAY at text that looks like a date but is not a real date value, which gives a #VALUE! error; convert it with DATEVALUE first.

Frequently asked questions

How do I make Monday equal 1?

Pass 2 as the second argument: =WEEKDAY(A2, 2) numbers Monday as 1 through Sunday as 7. Without it, the default return_type 1 makes Sunday 1 and Saturday 7.

How do I get the name of the day, not a number?

Use TEXT instead of WEEKDAY: =TEXT(A2, "dddd") returns the full day name such as "Wednesday", and "ddd" returns the short form "Wed".

How do I flag weekends with WEEKDAY?

Use return_type 2 and test for 6 or 7: =IF(WEEKDAY(A2, 2) > 5, "Weekend", "Weekday"). Because Saturday is 6 and Sunday is 7, anything above 5 is a weekend day.
