How to Add Days to a Date in Excel: Step-by-Step Guide

Do you need to increase the days in an Excel date? Here's a comprehensive guide with different methods for adding days to a date in Excel.

Method 1: Using the Excel DATE Function

The Excel DATE function is a built-in feature used to obtain the date value for a specific day, month, and year. This function takes three arguments: the year, the month, and the day. The year argument should be a four-digit year (yyyy), while the month argument should be a number from 1 to 12, representing the month, and the day argument should be a number from 1 to 31, representing the day of the month.

To employ the DATE function, you can either enter it directly into a cell or incorporate it into a formula. For instance, to add 7 days to the date in cell A1, you can use this formula:=DATE(YEAR(A1),MONTH(A1),DAY(A1)+7)

If you enter this formula into cell A2, it will display the date that is 7 days after the date in cell A1. You can also add days to a date using the DATE function by entering the function directly into a cell or employing a formula with a macro, custom function, or user-defined function.

Method 2: Using the Excel DAY, MONTH, and YEAR Functions

The DAY, MONTH, and YEAR functions in Excel are built-in features used to extract the day, month, and year components of a date, respectively. The DAY function requires a single argument, which is a date value. The MONTH function and the YEAR function both also take a single argument, which is a date value.

To use the DAY, MONTH, and YEAR functions, you can either enter them into a cell or include them in a formula. For example, to add 7 days to the date in cell A1, you can use the following formula:=DATE(YEAR(A1),MONTH(A1),DAY(A1)+7)

By entering this formula into cell A2, you will obtain the date that is 7 days after the date in cell A1.

Method 3: Using the Excel TEXT Function

The Excel TEXT function is a built-in tool for converting a value into text in a specified format. It requires two arguments: the value to be converted and the format to use. The value to be converted can be a number, a date, or a text string, and the format is determined by a format code.

To use the TEXT function, you can enter it into a cell or incorporate it into a formula. For example, to add 7 days to the date in cell A1, you can use the following formula:=TEXT(A1,"dd/mm/yyyy")+7

By entering this formula into cell A2, you will obtain the date that is 7 days after the date in cell A1. You can also use the TEXT function to add days to a date with a macro or a specific format by entering a macro that includes the desired format.

Method 4: Using an Excel Macro

If you need to add days to a date in Excel regularly, you can create a macro to automate the process. A macro is a set of instructions used to perform a task automatically. To create a macro, you should utilize a macro recorder, which records your actions as you perform the task.

You can create a macro to add days to a date in a specific format. For instance, to add 7 days to the date in cell A1 and display the resulting date in cell A2 in the dd/mm/yyyy format, you can use the following macro:Sub AddDays()Dim d As Dated = Range("A1").Valued = d + 7Range("A2").Value = Format(d,"dd/mm/yyyy")End Sub

This macro will add 7 days to the date in cell A1 and display the resulting date in cell A2 in the specified format. You can also use a macro to add days to a date by employing a custom function or a user-defined function. These functions can be integrated into a macro to obtain the desired result.
