As a growth manager at Excelmatic, I see teams wasting hours manually calculating dates in spreadsheets every week. But here's the secret: Google Sheets has built-in magic to handle date math automatically.
Let me show you three simple methods to add days to dates - no more counting on calendars!
Method 1: The Simple Addition Trick
Google Sheets treats dates as numbers behind the scenes. This means adding days is as easy as 1+1:
- Click on an empty cell
- Type
=A1+7(where A1 has your date and 7 is days to add) - Hit Enter
Pro tip: If the result looks weird, just format it as a date (Format > Number > Date). This method works great for quick calculations like adding 30-day trial periods or 7-day shipping estimates.
Method 2: The DATE Function (For Precise Control)
When you need bulletproof date math that handles month-ends and leap years, the DATE function is your best friend:
=DATE(YEAR(A1), MONTH(A1), DAY(A1)+10)
This formula:
- Automatically rolls over to next month if needed
- Works across year boundaries
- Stays accurate for February 29th
We use this at Excelmatic when calculating subscription renewals - it never messes up billing cycles!
Method 3: Dynamic Dates with TODAY()
Need dates that always stay current? Combine TODAY() with simple math:
=TODAY()+30 // Adds 30 days to current date
This automatically updates daily - perfect for:
- Countdown timers
- Expiration date trackers
- Recurring task reminders
