How the Weeks Calculator Works

This tool calculates the duration between two dates in terms of full weeks and any remaining days. It's useful for medium-term planning, such as tracking pregnancy milestones or project schedules that are measured in weeks.

How to Calculate Weeks Between Dates: The Formula

The algorithm first calculates the total number of days between the two dates, then divides by 7 to find the number of full weeks. The remainder is the leftover days.

Weeks = floor(Total Days / 7)
Remaining Days = Total Days % 7
