# Your Guide on How to Add Days in Excel

We can quickly add days and months to a date value in Excel. By following a few simple steps, this tutorial will guide any level of Excel in working with dates in Excel

## Setting up the Data

First, we will setup our data so that cell B2 will be the Date Value, cell B3 will be the Days to Add and cell B4 will be the Months to Add. We will then make the return value E2 Figure 1 – Setting up the Data

## Adding Days to a Date Value

We can add days to a date value by using a simple SUM formula

SUM Syntax:

`=SUM(Value 1, Value 2)`

• Enter a date in cell B2
• Type “10” in E2
• In cell E2, type this formula: =SUM(B2,10) Figure 2 – SUM Formula for Dates

We can see in this Example, the formula in E2 returns 1/11/18 because we added 10 days to 1/1/18

## Adding Months to a Date Value

The math equation to add months to a Date is Number of Months x Number of Days in Months, but we can’t do this in Excel because all months don’t have the same number of days in them. Therefore, we must account for this variance when creating our formula. We can use the EDATE function for this

EDATE Syntax:

`=EDATE(Starting Date, Number of Months)`

• Delete the days in cell B3
• Type “10” in cell B4
• In cell E2, type this formula =EDATE(B2,B4) Figure 3 – Adding Months to Date using EDATE

We can see in this example that the function automatically calculates the months and returns 11/1/18

Solved by F. C. in 40 mins I need a formula to combine D2 to D100 to add together a column of numbers, then take away the same amount on the same row when column E is filled. i.e. column D is a price of an item, so the formula must calculate the total, then when the item is sold an 'a' is marked next to the item in column E, the formula then must deduct this amount from the total

Solved by I. A. in 45 mins I am working on a cash flow projection. Part of the projection includes sales commissions. Our sales guys earn a monthly draw and then commission on sales after a certain amount. For example they may earn a monthly salary of 12,500 and earn additional commission after their commission equals \$150,000. What I need excel to do is sum a column if the values in the preceeding columns are greater than \$150,000. I've tried using the sumif and the if function in excel and it's not working correctly either way. Any suggestions?
