Are you tired of manually entering dates and times in your Excel spreadsheets? Do you struggle to calculate dates and times accurately? Well, you’re in luck Excel has a range of date and time functions that can make your life easier. In this comprehensive guide, we’ll explore four essential date and time functions in Excel: TODAY, NOW, EOMONTH, and WORKDAY.

What are Date and Time Functions in Excel?

Date and time functions in Excel are a set of formulas that allow you to work with dates and times in your spreadsheets. These functions can help you perform various tasks, such as:

• Entering the current date and time
• Calculating dates and times
• Formatting dates and times
• Extracting specific parts of a date or time

The TODAY Function

The TODAY function is one of the most commonly used date and time functions in Excel. It returns the current date, without the time. The syntax for the TODAY function is:

TODAY()

Here’s an example:

Formula	Result
=TODAY()	2023-02-20

The NOW Function

The NOW function is similar to the TODAY function, but it returns the current date and time. The syntax for the NOW function is:

NOW()

Here’s an example:

Formula	Result
=NOW()	2023-02-20 14:30:00

The EOMONTH Function

The EOMONTH function returns the last day of the month, a specified number of months before or after a date. The syntax for the EOMONTH function is:

EOMONTH(start_date, months)

Here’s an example:

Formula	Result
=EOMONTH(A1, 3)	2023-05-31

Assuming the date in cell A1 is 2023-02-20, the formula returns the last day of the month, 3 months after the date.

The WORKDAY Function

The WORKDAY function returns a date that is a specified number of workdays before or after a date. The syntax for the WORKDAY function is:

WORKDAY(start_date, days, [holidays])

Here’s an example:

Formula	Result
=WORKDAY(A1, 5)	2023-02-27

Assuming the date in cell A1 is 2023-02-20, the formula returns a date that is 5 workdays after the date.

Real-World Scenarios

Let’s explore some real-world scenarios where these date and time functions can be useful:

Scenario 1: Tracking Project Deadlines

Suppose you’re managing a project and need to track the deadlines. You can use the TODAY function to enter the current date and the EOMONTH function to calculate the deadline.

Project	Deadline
Project A	=EOMONTH(TODAY(), 2)
Project B	=EOMONTH(TODAY(), 3)

Scenario 2: Calculating Employee Workdays

Suppose you’re an HR manager and need to calculate the number of workdays an employee has taken off. You can use the WORKDAY function to calculate the number of workdays.

Employee	Start Date	End Date	Workdays
John	2023-02-10	2023-02-20	=WORKDAY(A2, B2)

Scenario 3: Generating Reports

Suppose you’re a financial analyst and need to generate reports on a monthly basis. You can use the NOW function to enter the current date and time.

Report Date	Report Time
=NOW()	=NOW()
