How long between 2 dates

You can, of course, calculate the days or time between two dates manually, and should you wish to go down that route you'll need to remember how many days there are in each month. We know that there's days in a regular year. If there's a leap year involved then an extra day is added. A leap year occurs every 4 years and means that February has 29 days instead of February has 28 alone or 29 in a leap year , And all the rest have So, calculating the number of days between two given dates isn't the easiest task because of the way in which our Gregorian calendar works we've been using the Gregorian calendar for over years, but many people question why we still use it.

The days between dates calculator on this page works by getting the time stamp of the start date and deducting it from the end date or vice-versa if the end date is in the past before calculating the number of hours, days and years between them. To calculate the number of days since you were born , simply enter your date of birth as the start date and then ensure that the end date is set to today's date if it isn't already set, click the 'today' link that appears to the right of the box.

Then click the 'Calculate' button. Alternatively, you could give my age calculator a try. Try it: enter the day and the next date and you'll get '1', not '2' or '0' days in between.

Yes, it sure does. Years are abstractions though, so unless you try to deliberately bracket February 29 in a leap year you might not even know a leap year is in the calculation. However, leap years are in the tool. If you see a day difference that looks "off by one", it's actually correct and you're seeing the extra leap year day counted.

INTL function when you want to calculate the number of workdays between two dates. You can also have it exclude weekends and holidays too. Before you begin: Decide if you want to exclude holiday dates. If you do, type a list of holiday dates in a separate area or sheet. Put each holiday date in its own cell. Name the range MyHolidays , and click OK. Then create the formula using the steps below. Type a formula like the above example. The 1 in the formula establishes Saturdays and Sundays as weekend days, and excludes them from the total.

INTL function. If Saturday and Sunday are not your weekend days, then change the 1 to another number from the IntelliSense list. For example, 2 establishes Sundays and Mondays as weekend days. If you are using Excel , skip this step. If you don't have holidays, you can leave the comma and MyHolidays out.

Or, you could type each holiday inside the formula. You can calculate elapsed time by subtracting one time from another. First put a start time in a cell, and an end time in another. Make sure to type a full time, including the hour, minutes, and a space before the AM or PM. In this example, the start time is in cell D80 and the end time is in E Make sure to type the hour, minute, and a space before the AM or PM.

To calculate the time between two dates and times, you can simply subtract one from the other. However, you must apply formatting to each cell to ensure that Excel returns the result you want. Each cell should have a month, day, year, hour, minute, and a space before the AM or PM. Unknown start date.
