Date Calculator
Calculate what date falls X days, weeks, or months from any date. Free date calculator with business days mode and day-of-week output.
The Complexity of Simple Date Addition
While adding 7 days to a date is straightforward, adding months or counting business days introduces significant complexity. Months vary from 28 to 31 days, and leap years shift the calendar every four years. Our calculator handles these variables automatically to ensure your deadlines are always accurate.
Standard US Business Deadlines
Many professional agreements in the US rely on specific day counts. A 30-day return policy, a 60-day notice period, or a 90-day probationary period are standard across industries. Knowing exactly which day of the week a deadline falls on is critical for scheduling meetings and avoiding weekend expirations.
Date Math for Project Milestones
Effective project management often requires working backwards from a target date or building in buffers. By using the 'Subtract' mode, you can determine when a phase must start to meet a final deadline, accounting for both calendar days and working weeks.
