Week Calculator
Use the week calculator to find out how many weeks and days are between two dates.
What Week Calculator does
The Week Calculator determines the number of full weeks and additional days between any two dates. Users enter a starting date and an ending date, and the tool instantly returns the duration in complete weeks plus remaining days, making it useful for project timelines, event planning, or tracking gestation periods. The result also indicates which week and day of the week each input date falls on. Compared to other time calculators on the site, this version focuses exclusively on the week-and-days breakdown, offering a simpler interface that skips month or year conversions unless the user navigates to the day counter or month calculator linked nearby. It includes brief explanatory text on counting weeks and leap year facts, but does not provide unit switching within a single result. The design is minimal, with fields labeled "Starting day" and "Last day" and a "Share result" button for easy export.

Week Calculator FAQ
- Can I calculate weeks between dates that span different months or years?
- The starting day is not counted; the duration runs from the day after the start date up to and including the last day.
- Does the calculator count the starting date as week zero?
- No, the starting day is excluded from the counting, so the result reflects the weeks and days after the start date.
- What if I need the total number of days instead of weeks?
- The site offers a separate day counter tool for total days between dates; the week calculator focuses on the weeks‑and‑days breakdown.
