Count days and plan deadlines
Find out how many days, weeks and working days are left until a deadline, holiday or due date, or work out what date it will be 90 days from today.
常见问题
Does it count the end date?
By default it counts the days between the two dates. Tick “Include the end date” to count both the first and last day, as you would for a hotel stay or a leave request.
What are working days?
Monday to Friday. Public holidays are not removed, because they differ by country.
