# Excel DATE function

## Summary

The Excel DATE function is used to create a date from individual year, month, and day components. It is especially valuable for constructing dates that need to dynamically respond to changes in a worksheet or for creating dates based on calculations. The DATE function ensures that the dates created are valid and interpretable by Excel as serial date numbers.
##### Syntax
```				```
=DATE(year, month, day)
```
```
• year: The year component as a number.
• month: The month component as a number.
• day: The day component as a number.
##### Return value
A serial number representing a valid Excel date.

## How to use

To create a date, provide the year, month, and day as separate numerical arguments to the DATE function. The function will return a serial number that Excel recognizes as a date. To view this number as a standard date, apply a date format to the cell. The DATE function is particularly useful when you need to create dates based on dynamic inputs or calculations within your worksheet.

## Examples

##### Simple DATE
Creating a Specific Date: To create a specific date based on individual components:
```				```
=DATE(2022, 12, 25)
```
```
This formula constructs the date for December 25, 2022.
##### DATE and TODAY
Dynamic Birthday Reminder: To remind you of an upcoming birthday every year:
```				```
=DATE(YEAR(TODAY()), 5, 20)
```
```
This formula creates a date for May 20th of the current year, dynamically updating each year.
##### DATE with Calculations
Project Deadline Calculation: To calculate a project deadline based on a start date and duration:
```				```
=DATE(YEAR(A1), MONTH(A1) + 6, DAY(A1))
```
```
Assuming the start date is in cell A1, this formula calculates the deadline as 6 months after the start date.
