#DATE AND TIME CALCULATOR ADD AND SUBTRACT HOW TO#
#DATE AND TIME CALCULATOR ADD AND SUBTRACT SERIAL NUMBERS#

If you prefer to supply the dates directly in the formula, then enter each date using the DATE(year, month, day) function and then subtract one date from the other.įor instance, the following formula subtracts 1 from 2 and returns the difference of 5 days: Subtracting dates with Excel DATE function Like in the previous example, both formulas work fine when today's date is greater than the date you are subtracting from it, otherwise DATEDIF fails:Įxample 4. Just use the TODAY() function instead of date 1: To subtract a date from today's date, you can employ either of the above formulas. The syntax of the Excel DATEDIF function, however, does not allow the start date to be greater than the end date and therefore it returns an error.Įxample 3. When you subtract a more recent date () from an earlier date (), the subtraction operation returns a negative number (-5) exactly as it should.

The following screenshot demonstrates that both calculations return identical results, except for row 4 where the DATEDIF function returns the #NUM! error. If the above formula looks too plain, you can achieve the same result in a guru-like way by using Excel's DATEDIF function: Subtract dates using Excel DATEDIF function So, you are actually subtracting two numbers, and an ordinary arithmetic operation works without a hitch:Įxample 2.

Subtract one date from the other directlyĪs you probably know, Microsoft Excel stores each date as a unique serial numbers beginning with 1 that represents January 1, 1900. As is often the case in Excel, the same result can be achieved in several ways. So if you want to count the days between two dates, then check out the day counter, and if you are looking to determine the duration between times, then make sure to give a read to OMNI's time duration calculator.Supposing you have two dates in cells A2 and B2, and now you want to subtract one date from the other to know how many days are between these dates. We are here to help you with as many time, and date needs as possible. Another method is to add hours to hours, minutes to minutes, seconds to seconds (weeks to weeks, etc.) Let's say you want to add 3 h 54 min 46 s to 19 h 33 min 55 s:Ĭonvert the result to hours - divide minutes by 60 and leave the remainder as minutes:Ģ2 h + 1 h 27 min + 1 min 41s = 23 h 28 min 41 s For example, if you have to subtract 1 h 20 min 30 s from 2 h 14 min 16 s, you may first convert them to seconds, and we have a time unit converter to assist you for that:Ĭonvert the result to the target unit by dividing it by 60 (the remainder becomes the seconds):

Now, let's go through some examples of how to add and subtract time when you don't have access to time math calculators.Ĭonvert Time 1 and Time 2 to simpler units if you need to.

It allows you to calculate between two dates. While seconds and hours obey the sexagesimal system:īefore we get into it, may we interest you to check out our date calculator. It's probably because we're used to using the decimal system: Adding and subtracting time on your own can be confusing.
