Frequently asked questions
How do I count the days between two dates?
Pick the start and end dates. You get the number of days, weeks, months and working days (Monday to Friday) between them. Tick "include end date" to count both days.
How do I find the date 90 days from today?
Use "Add or subtract days": keep today as the date, enter 90 and press Add.
Does it count holidays?
Working days exclude Saturdays and Sundays only. Subtract public holidays yourself, as they differ by state and company.
