Subtract the earlier date from the later date. The calculator automatically handles leap years and different month lengths. For example: January 1 to March 1, 2024 = 60 days (leap year).

Divide the number of days by 7. For example: 60 days / 7 = 8 weeks and 4 days. The calculator shows days, weeks, and months.

A leap year has 366 days instead of 365. It occurs every 4 years (divisible by 4), except years divisible by 100 that are not divisible by 400. For example: 2024 is a leap year, 2100 is not.
