Let’s be real—Excel date calculations can be confusing AF. You’re trying to plan a project timeline or schedule future events, and suddenly you’re drowning in spreadsheet formulas. But here’s the good news: adding weeks to a date is way easier than you think, especially when you’ve got modern AI tools like Excelmatic in your corner.
Why Dates in Excel Are Just Numbers in Disguise
Here’s the secret sauce: Excel treats dates as serial numbers. January 1, 1900 = 1, January 2, 1900 = 2, and so on. This means adding weeks is just basic math—no magic required.
Try this:
- Type any date in cell A1 (e.g., 3/15/2024)
- Change the cell format to "General"
- Boom—you’ll see a number like 45350. That’s Excel’s way of saying "March 15, 2024."
The Simple Formula You Need
Want to add 5 weeks to today’s date? Here’s your golden ticket:
=A1 + (5*7)
Breaking it down:
A1= your starting date5*7= converting weeks to days (because 1 week = 7 days)
