A Date Calculator is a tool or utility used to perform calculations related to dates, such as adding or subtracting days, weeks, months, or years, calculating the difference between two dates, and more. Date calculations are commonly used in project planning, financial analysis, scheduling, or general time management.
Common Date Calculations:
Add/Subtract Days, Weeks, Months, or Years:
You can add or subtract a specific number of days, weeks, months, or years to/from a given date.
Example: Adding 10 days to "March 1, 2025" gives "March 11, 2025."
Date Difference:
Calculate the difference between two dates in terms of days, months, or years.
Example: The difference between "March 1, 2025" and "March 11, 2025" is 10 days.
Current Date:
Find the current date, often used as a reference point for other calculations.
Week Number:
Find the week number of the year for a given date.
Example: "March 1, 2025" is in Week 9 of the year.
Day of the Week:
Calculate the day of the week for a specific date (e.g., "March 1, 2025" is a Saturday).
Date Validation:
Check whether a specific date is valid (e.g., if the date is "February 29" in a leap year).
Working Days/Weekdays Calculation:
Calculate the number of working days (weekdays) between two dates, excluding weekends and public holidays.
Example: The number of weekdays between "March 1, 2025" and "March 10, 2025."
Date Formatting:
