दिनांक कैलकुलेटर क्या है?

A date calculator performs date-related calculations: difference between two dates, add or subtract time periods (years, months, weeks, days), days since a past date or until a future date, and which day of the week a date falls on. It handles leap years, varying month lengths, and year boundaries.

Difference = End Date − Start Date  |  Business days = weekdays only (Mon–Fri)

Use it for project planning, countdowns, age or tenure, deadlines, and scheduling.

Date Format

Use YYYY-MM-DD (e.g. 2025-02-15). Dates from year 1 to 9999 are supported.
