Google Sheets Date Formula Examples

Use Google Sheets date formulas for deadlines, due dates, day counts, month logic, and simple schedule calculations.

Google Sheets date formulas help with due dates, date differences, month boundaries, and schedule calculations. The key is to keep real dates as dates, not text.

Check this first

Confirm the cells are true dates, not text that looks like dates.
Use TODAY for dynamic current-date logic.
Format the result cell as a date when needed.
Test date differences separately before nesting them inside IF logic.

Working examples

Add 30 days to a start date

=A2+30

Days remaining until a due date

=B2-TODAY()

Why date formulas break so often

Most date issues are not about the formula itself. They come from imported text, inconsistent formats, or hidden time values. Once the source cells are true dates, many formulas become much simpler than people expect.

That is why a date formula page should always start with date sanity checks before advanced logic.

Useful everyday patterns

The most common date tasks are adding days, counting days between events, flagging overdue work, and rolling due dates forward. These are strong SEO targets because they map to real office tasks rather than abstract formula theory.

Days until a deadline.
Days between two dates.
Next billing or renewal date.
Overdue flagging with TODAY.

Keep dates numeric under the hood

In spreadsheets, dates are values first and display formats second. Treating them like text too early leads to fragile formulas and confusing comparisons.
