Days Calculator – Calculate Days, Weeks, and Months Between Two Dates
The days calculator precisely determines how many days, weeks, or months exist between two dates. Enter start and end dates to get an exact result.
The tool accounts for leap years and varying month lengths. It also shows the day of the week for each date and calculates how many weekdays and weekend days the period contains. Perfect for project timelines, anniversaries, and event planning.
How many days are in a year?
A regular year has 365 days and a leap year has 366. Leap years occur every four years (e.g., 2024, 2028), except at century turns, when the year must be divisible by 400. A year has 52 weeks and 1–2 extra days. The calculator handles these automatically.
