![]() ![]() How to subtract or add days to date in Excel There are a number of Excel functions suitable for this purpose, and which one you use depends on which unit you want to add or subtract. Now that you know how to subtract two dates, let's see how you can add or subtract days, months, or years to a given date. If you are looking to count the number of months or years between two dates, then the DATEDIF function is the only possible solution and you will find a few formula examples in the next article that will cover this function in full details. Wrapping up, when it comes to subtracting dates in Excel and you want to find out how many days are between two dates, it makes sense to go with the easiest and most obvious option - simply subtract one date directly from another. ![]() 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. Answer: you have 5 Days 9 Hours 30 Minutes free time left.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 will find out how much free time you will have by subtracting 38 hours and 30 minutes from 1 week. You know that the work itself will take you 38 hours 30 minutes. We all know how many days in a year, but what if we want to know how many seconds are in a year?Įxample:Let's imagine that you were given one week to complete the work and you need to plan a schedule. With it, you can express any time unit in other units, actually in all of them at the same time. The new date and time will be calculated immediately and presented in a convenient way.Īnd the last calculator, it can even be called a time units converter. Just enter the initial parameters and the required time interval. In two simple steps, add and subtract days, hours, minutes and seconds in any combination.Īdding or subtracting time from the current date is also not difficult. ![]() Unlike simple mathematical addition and subtraction, it is not so easy to do when it comes to time and dates, because each unit is not decimal and can contain 60, 24 or even 365 other units, not 10 or 100 as we are used to in normal math. The first is basically calculating the time. The Time Calculator has very wide functionality and can be useful for various occasions. ![]()
