What Does Days Between Dates Mean?
It is the calendar-day distance between a starting date and an ending date. The total can be shown as days, weeks and days, or a calendar-aware duration.
Calendar Days vs. Working Days
Calendar days include every day in the selected range. Working-day counts exclude selected weekends and holidays, so the totals are different.
Common Days Between Dates Questions
How many days are between two dates?
Choose the first date and the second date, then calculate the difference. The result helps answer searches such as “how many days between dates,” “days between two dates,” and “calculate days between dates.”
How do I count days from one date to another?
Enter the start date and end date. Use the inclusive date option if you want to count both the starting day and ending day. Otherwise, the date difference is the elapsed number of calendar days between them.
How many weeks are in the date range?
Divide the total calendar days into complete seven-day weeks and remaining days. Month and year breakdowns are calendar-based because months do not all have the same length.
Use this free date-to-date calculator for countdowns, event planning, vacation lengths, project timelines, age-related date checks and everyday questions. Calendar days include weekends; use the Business Days Calculator when you need working days instead.
