Calculate dates between two dates, add or subtract days, and discover the day of the week for any date.
Quickly find out how many days, weeks, or months lie between any two dates — useful for deadlines, countdowns, and planning.
Add or subtract any number of days from a starting date to find a target date — perfect for scheduling and project management.
Enter any past or future date to instantly find out which day of the week it falls on — handy for historical dates or planning events.
This date calculator combines three practical tasks in one place: counting the number of days between two dates, adding or subtracting days from a selected date, and finding the weekday for any date. That makes it useful for planning deadlines, renewals, travel, event schedules, exam dates, delivery targets, and general calendar math.
Instead of working things out manually, you can get a quick answer and move on. If you are planning across timelines, progress rates, or age-based dates, the Age Calculator, Percentage Calculator, and Loan Calculator are also useful companion tools.
Check how many days remain until an exam, add 45 days to an invoice date for follow-up planning, or find which weekday a birthday or appointment will fall on.
Students, teams, freelancers, and families can all use it to estimate time gaps, schedule milestones, and keep deadlines visible.
The page gives you a clean result without spreadsheet formulas, including days, approximate weeks and months, and the exact target date.
