# How to Add One Month to a Date in Excel?

If you work with dates in Excel, you know that it can be tricky to add one month to a date. Managing dates in Excel requires more than just basic knowledge of the program, but with a few simple steps, you can easily add one month to any date in Excel. In this article, we will walk you through the steps of how to add one month to a date in Excel.

## Adding One Month to a Date in Excel

Excel is a powerful spreadsheet program that allows users to analyze and present data in visual ways. It also has a number of powerful tools that allow users to manipulate dates and times. One of the most useful of these tools is the ability to add one month to a date in Excel. In this article, we will look at how to add one month to a date in Excel, as well as some other related tips and tricks.

### Using the Date Function

The easiest way to add one month to a date in Excel is to use the Date function. This function takes a year, month, and day argument, and returns the corresponding date. To add one month to a date, you would use the following formula: Date(YEAR, MONTH + 1, DAY). For example, if the date is June 1, 2021, you would use the following formula: Date(2021, 6+1, 1).

#### Determining the Last Day of the Month

If the last day of the month is not known, the Date function can be used to determine it. The Date function can be used in conjunction with the Day function to calculate the last day of the month. The Day function will take the year, month, and day arguments and return the corresponding day of the week. To determine the last day of the month, you would use the following formula: Date(YEAR, MONTH + 1, 1) – Day(YEAR, MONTH + 1, 1).

#### Automatically Updating Dates

If you need to add one month to a date in Excel and have the date automatically update, you can use the EDATE function. This function takes a date and a number of months as arguments, and returns the corresponding date. For example, if the date is June 1, 2021, and you want to add one month, you would use the following formula: EDATE(2021-06-01, 1). This will return the date July 1, 2021.

### Using Conditional Formatting

Excel also allows users to add one month to a date using conditional formatting. This feature allows users to define rules based on the values in a cell, and then apply formatting automatically when those rules are met. To add one month to a date in Excel using conditional formatting, you would first select the range of cells that contain the dates. Then, you would create a new rule and select the “Format only cells that contain” option.

#### Selecting the Criteria

Next, you would select the criteria for the rule. You would select “Date” as the data type, and then select “Ends with” for the operator. You would then enter “+1M” in the value field, which will add one month to the date. The final step is to select the formatting that should be applied when the rule is met. You can select any formatting that you want, such as bold, italic, or color.

### Using a Macro

Excel also allows users to add one month to a date using a macro. This is a more advanced option and requires some knowledge of VBA (Visual Basic for Applications). To add one month to a date in Excel using a macro, you would first create a new module in the VBA editor. Then, you would enter the following code:

Dim Date As Date
Date = Range(“A1”)
Date = Date + 1
Range(“A1”) = Date

This code will add one month to the date in cell A1. You can adjust the code as necessary to add one month to any date in Excel.

### Using the NOW Function

The NOW function is an Excel function that returns the current date and time. This function can be used to add one month to a date in Excel. To do this, you would use the following formula: NOW() + 30. This will add 30 days to the current date, which is equivalent to one month.

### Using the DATEVALUE Function

The DATEVALUE function is an Excel function that takes a text string as an argument and returns the corresponding date. This function can be used to add one month to a date in Excel. To do this, you would use the following formula: DATEVALUE(“Month + 1”). This will add one month to the current date.
