Common questions
How does the calculator handle different month lengths?
The calculator uses calendar-based arithmetic, correctly accounting for months with 28-31 days and leap years. A period from January 31 to February 28 counts as 1 month, not 28 days.
Can I calculate the date after adding days?
This tool calculates the difference between two dates. Enter your start date in one field and let the end date be today to see elapsed time, or enter both dates to find the duration between them.
