Understanding Excel Date Functions
Excel provides a wide range of date functions that allow you to manipulate and format dates in various ways. These functions can be used to calculate the difference between two dates, extract specific components of a date, and even add or subtract a certain number of days, months, or years to a date. In this section, we’ll take a closer look at some of the most commonly used date functions in Excel.
The Formulas Tab
To access the date functions in Excel, you’ll need to navigate to the Formulas tab. Here, you’ll find a wide range of functions that can be used to manipulate dates, including TODAY, NOW, DATE, YEAR, MONTH, and DAY.
The TODAY Function
The TODAY function is one of the most commonly used date functions in Excel. It allows you to insert the current date into a cell, which can be useful for tracking information that is time-sensitive. To use the TODAY function, simply type “=TODAY()” into the cell where you want to insert the current date.
