## Types of date formulas in Excel

There are various date formulas in Excel that one can use to make calculations based on dates. These formulas are designed to simplify date calculations and work with different date formats.

TODAY()Returns the current date
DATE()Creates a date by entering the year, month, and day as separate arguments
YEAR()Returns the year of a specified date
MONTH()Returns the month of a specified date
DAY()Returns the day of a specified date
WEEKDAY()Returns the day of the week as a number from 1 to 7
DATEDIF()Calculates the number of days, months, or years between two dates

It is essential to use the correct formula based on the required output and date format. For instance, the YEAR() formula may not work with a date format that does not include the year.

The DATEDIF() formula is not documented on Excel but is known to exist and is relatively useful for calculating the difference between two dates.

Interestingly, the TODAY() formula updates every time the worksheet is opened, making it a useful tool for tracking time-sensitive information.

The use of date formulas in Excel dates back to the early 2000s when Microsoft introduced date and time functions to its software suite.

Overall, understanding the various date formulas in Excel is essential for efficient and accurate data processing.

## How to use the DAY formula in Excel

The DAY formula in Excel is a useful tool for extracting the day from a date value. It can be used for various purposes, including filtering and sorting data by day. Here is a 6-step guide on how to use the DAY formula in Excel:
