Week Calculator: Know How Many Weeks Between Dates!
Okay, let's be honest — calculating weeks between two dates in your head? Not fun. Is it 6 weeks or 7? Do we count this Monday? What about leap years or partial weeks?
That's where a Week Calculator comes in handy. It does the work for you — no counting on fingers, no calendar scrolling, no mental math.
🔍 What Is a Week Calculator?
A Week Calculator is a simple tool that tells you the number of weeks (and days, if needed) between two dates.
You plug in a start date and an end date, and in just a second or two, it shows you:
- Total number of full weeks
- Extra days (if dates don't align perfectly)
- Sometimes months and weekdays too
And that's it. Easy, right?
