Date Calculator: Count Days

Date Calculator has two tools on one screen. Count Days measures the exact time between two calendar dates in years, months, weeks, days, hours, minutes and seconds. Add/Subtract moves a date forward or back by any mix of years, months, weeks and days. Both show the dates on a month calendar, so you can see where they fall.

Count Days
• Start and end date, with an option to include the end day in the count
• Result in years, months, weeks and days, plus the same span in total days, hours, minutes and seconds
• Optional holidays: enter a month and day, such as December 25, to count them or leave them out

Add or subtract
• A start date, then years, months, weeks and days in any combination
• Optional exclusion of holidays from the result
• The new date shown on a calendar

Where it helps
• Counting days to a deadline, due date or notice period
• Working out a contract end date, a warranty expiry or a 90-day trial
• Finding the exact age of a document, a pet or a project
• Planning a date that is six weeks or two years away
