Our versatile date calculator supports multiple operations for comprehensive date arithmetic:
The calculator provides detailed information including date properties, business days, weekends, holidays, and time breakdowns depending on your selected operation.
Add years, months, days, hours, and minutes to a starting date to find a future date. Useful for scheduling, planning deadlines, or calculating maturity dates.
Subtract time periods from a date to find when something started or to backtrack from a known end date.
Find the exact time difference between two dates with comprehensive breakdowns including business days and weekend counts.
Business day calculations are essential for project management, financial planning, and professional scheduling. Our calculator automatically excludes weekends and provides separate counts for different day types.
