# Excel Tutorial: How To Make Date Change Automatically In Excel

## Introduction

When working with spreadsheets in Excel, automatically changing dates can be a crucial feature. Whether it's for project timelines, financial records, or scheduling tasks, having dates update automatically can save time and reduce errors. In this tutorial, we will provide a brief overview of the steps to achieve this, helping you to streamline your Excel workflow and improve accuracy in your data management.

## Key Takeaways

• Automatically changing dates in Excel is crucial for saving time and reducing errors in data management.
• The DATE function allows for the creation and manipulation of dates in Excel.
• The TODAY function can be used to automatically update dates to the current date.
• The OFFSET function offers a way to dynamically change dates based on a reference date.
• The EOMONTH function is useful for creating dynamic date ranges in Excel.

## Understanding the DATE function in Excel

When working with dates in Excel, it is essential to understand the DATE function, which allows you to create a date based on the year, month, and day values you specify. The DATE function is particularly useful for automatically updating dates in your Excel spreadsheets.

A. Explanation of how the DATE function works

The DATE function takes three arguments: year, month, and day. These arguments must be valid date values, and you can input them directly or reference cells that contain the date values. The function then returns the corresponding date in Excel's date format.

B. Examples of how to use the DATE function

Here are a few examples of how to use the DATE function:

• ### Example 1:

Using direct input

=DATE(2023, 8, 15) - This formula will return the date August 15, 2023.

• ### Example 2:

Referencing cells

=DATE(A1, B1, C1) - Assuming cells A1, B1, and C1 contain the year, month, and day values, this formula will return the corresponding date.

• ### Example 3:

Using other functions

=DATE(YEAR(TODAY()), MONTH(TODAY()), DAY(TODAY())) - This formula will return today's date, and it will update automatically when the spreadsheet is recalculated or opened on a new day.

## Using the TODAY function for automatic date updates

Keeping track of dates in Excel can be a hassle, especially when you have to manually update them every day. Fortunately, Excel has a function called TODAY that can automatically update the date for you.

A. Explanation of the TODAY function

The TODAY function in Excel returns the current date. It does not require any arguments and is simple to use. The function updates the date every time the worksheet is recalculated, making it a useful tool for automatically updating dates.

B. Steps to implement the TODAY function for automatic date updates

### Step 1: Select the cell where you want the date to appear

First, select the cell in which you want the current date to appear. This could be in a specific cell where you want the date to be displayed, or it could be part of a formula or function within a cell.

### Step 2: Enter the TODAY function

Once you have selected the cell, type =TODAY() into the formula bar and press Enter. The current date will immediately appear in the selected cell, and it will update every time the worksheet is recalculated.

### Step 3: Utilize the date for your needs

Now that the TODAY function is implemented, you can use the date for whatever purpose you need. You can use it in calculations, as part of a conditional formatting rule, or simply as a reference for the current date.

## Utilizing the OFFSET function for dynamic date changes

When working with dates in Excel, it can be helpful to have them change automatically based on certain criteria or conditions. This is where the OFFSET function comes in handy, allowing you to create dynamic date changes in your Excel spreadsheets.

### Explanation of the OFFSET function

The OFFSET function in Excel returns a reference to a cell or range of cells that is a specified number of rows and columns from a specific cell or range of cells. This function is commonly used to dynamically retrieve data from a particular cell or range based on changing criteria.

### Examples of how to use the OFFSET function for dynamic date changes

Here are a few examples of how you can use the OFFSET function to create dynamic date changes in Excel:

• Example 1: Automatically updating the end date of a project schedule
• To automatically update the end date of a project schedule based on the duration of the project, you can use the OFFSET function to reference the start date cell and add the number of days for the project duration.

• Example 2: Creating a rolling date range for data analysis
• If you need to create a rolling date range for data analysis, you can use the OFFSET function to dynamically adjust the start and end dates based on a specified number of days or months.

• Example 3: Automatically updating due dates for tasks
• To automatically update due dates for tasks based on their start dates and durations, you can use the OFFSET function to calculate the end date and display it in a separate cell.

These examples demonstrate the flexibility and power of the OFFSET function for creating dynamic date changes in Excel. By leveraging this function, you can automate the updating of dates in your spreadsheets, saving time and reducing the risk of errors.

## Creating a dynamic date range with the EOMONTH function

Excel provides a powerful function called EOMONTH that can be used to create a dynamic date range that automatically updates based on the current date. This function is especially useful for financial modeling, budgeting, and forecasting where you need to project future dates.

A. Explanation of the EOMONTH function

The EOMONTH function is a built-in function in Excel that returns the last day of the month, a specified number of months before or after a given date. It takes two arguments: the start date and the months. For example, =EOMONTH(A2, 0) will return the last day of the month for the date in cell A2, =EOMONTH(A2, 1) will return the last day of the next month, and so on.

B. Steps to create a dynamic date range using the EOMONTH function

Creating a dynamic date range using the EOMONTH function involves a few simple steps.

• Step 1: Enter the start dateBegin by entering the start date in a cell within your Excel worksheet.
• Step 2: Use the EOMONTH functionIn a separate cell, enter the EOMONTH function with the start date and the number of months to add or subtract. For example, =EOMONTH(A2, 0) will return the last day of the current month based on the date in cell A2.
• Step 3: Drag the formulaOnce you have the EOMONTH formula in place, you can drag it down or across to create a dynamic date range for future months or years.

## Using conditional formatting to automatically update dates

Excel users often encounter the need to have dates automatically update based on certain conditions. This can be efficiently achieved through the use of conditional formatting. Conditional formatting allows users to apply formatting to cells based on specific criteria, which can also be used to automatically update dates.

### Explanation of how conditional formatting can be used for automatic date updates

Conditional formatting in Excel can be used to set up rules that will automatically change the date in a cell based on certain conditions. This can be particularly useful for recurring tasks or deadlines, where the date needs to be adjusted automatically without manual intervention.

### Steps to apply conditional formatting for automatic date changes

• Select the cell: Start by selecting the cell where you want the date to be automatically updated based on conditions.
• Open the conditional formatting menu: Go to the "Home" tab, click on "Conditional Formatting" in the "Styles" group, and select "New Rule."
• Choose a rule type: In the "New Formatting Rule" dialog box, select the rule type that corresponds to the condition you want to apply for the automatic date change. For example, you can choose "Format only cells that contain" or "Use a formula to determine which cells to format."
• Set the condition: Follow the prompts to set the condition for the automatic date change. This can include specific dates, text values, or formulas that need to be met for the date to update.
• Format the date: After setting the condition, choose the formatting options for the automatically updated date. This can include changing the font color, filling the cell with a color, or applying a specific date format.
• Apply the rule: Once the condition and formatting are set, click "OK" to apply the conditional formatting rule to the selected cell.

## Conclusion
