Calculate the difference in weeks between two dates using the ISO week date system.
How It Works
The ISO Week Difference Calculator uses a straightforward formula to determine the number of weeks between two dates. Here's the breakdown:
- It calculates the total number of milliseconds between the two dates (because even computers love precision!).
- Then, it converts those milliseconds into weeks by dividing by the number of milliseconds in a week (that's 604,800,000 milliseconds, in case you were curious).
- Finally, it rounds down to the nearest whole number to give you the exact number of weeks.
For example, if you want to know how many weeks are between January 1, 2023, and March 1, 2023, the tool will do the math and tell you it's 8 weeks. Easy, right?
