How to Add Today's Date in Excel

What this does

TODAY returns the current date; NOW returns the date with the time attached. Both are volatile: they recalculate whenever anything in the workbook changes, so a cell holding =TODAY() is not a record of when something happened, it is always "now". That is the single most consequential thing to know about them — a timestamp meant to stay put must be entered with Ctrl+; (date) or Ctrl+Shift+; (time), or pasted as a value. Their genuine use is anything that should move with the calendar: ageing an invoice, counting days remaining, driving a conditional format for overdue rows. 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 “add today's 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 layout choice that keeps the sheet readable and sortable, but the practical win is that someone else can open the file and understand what happened without asking you.

A worked example

Days a receivable has been outstanding: =TODAY()-A2, formatted as a number rather than a date. Flagging overdue rows with conditional formatting: =AND(A2<TODAY(), B2<>"Paid"). Days remaining until a deadline: =A2-TODAY(). A static stamp instead — press Ctrl+; which types the date once and never changes it. TODAY and NOW are what make an ageing report age itself — and knowing they are volatile is what stops them being used as timestamps. 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 “add today's 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

• Using =TODAY() as a record of when something was entered, which rewrites itself every time the file opens.
• Formatting a date difference as a date, which shows 1900-01-15 instead of 14 days.
• Forgetting the brackets; =TODAY without them returns #NAME?.
