How to Calculate Days Between Two Dates
Select a start date and an end date. Zelmric measures the calendar-day interval and also breaks the result into whole weeks, weekdays and weekend days.
Inclusive and Exclusive Date Counting
Date differences can vary by one day depending on whether the endpoints are counted. By default, Zelmric excludes the start date and includes the end date. Enable inclusive counting when both dates should count.
Weekdays and Weekend Days
The breakdown classifies Monday through Friday as weekdays and Saturday and Sunday as weekend days. It does not automatically remove public holidays.
Date Difference Examples
This tool can be used for project durations, travel intervals, event planning, elapsed-day checks and other questions that ask how many days separate two calendar dates.
