Date and Time Functions in Excel (Easy Guide for Beginners)

Date and time functions in Microsoft Excel are very useful when you need to manage schedules, track deadlines, calculate ages, monitor attendance, or analyze data based on dates. Many beginners feel confused when working with dates and time in Excel, but once you understand the basic functions, it becomes very simple.

In this guide, you will learn the most commonly used Date and Time Functions in Excel with easy explanations and examples.

What Are Date and Time Functions in Excel?

Date and time functions are built-in formulas in Excel that help you:

• Get the current date or time
• Extract parts of a date (year, month, day)
• Calculate the number of days between dates
• Add or subtract dates
• Manage schedules and deadlines

Excel stores dates as numbers, which allows it to perform calculations easily.

For example:

• January 1, 2026 = 45292 (Excel serial number)

This system allows Excel to calculate differences between dates automatically.

1. TODAY Function

The TODAY function returns the current date automatically.

Formula

=TODAY()

Example

If today is March 15, 2026, Excel will display: 3/15/2026

When to Use TODAY

You can use this function to:

• Track deadlines
• Calculate age
• Monitor due dates
• Create dynamic reports

Example: Calculate Days Remaining

If a deadline is in cell A1, you can calculate remaining days:

=A1-TODAY()

This will show how many days are left before the deadline.

2. NOW Function

The NOW function returns the current date and time.

Formula

=NOW()

Example Output: 3/15/2026 10:30 AM

When to Use NOW

Use this function when you need:

• Timestamp for reports
• Attendance tracking
• Real-time updates

3. DATE Function

The DATE function creates a date using year, month, and day.

Formula

=DATE(year, month, day)

Example: =DATE(2026,3,15)

Result: 3/15/2026

Why Use DATE?

It helps avoid errors when combining numbers into a date.

Example: =DATE(A1,B1,C1)

If:

A1 = Year
B1 = Month
C1 = Day

Excel will generate the correct date.

4. YEAR Function

The YEAR function extracts the year from a date.

Formula

=YEAR(date)

Example

If A1 contains: 3/15/2026

Formula: =YEAR(A1)

Result: 2026

5. MONTH Function

The MONTH function extracts the month number from a date.

Formula

=MONTH(date)

Example

If A1 contains: 3/15/2026

Formula: =MONTH(A1)

Result: 3 (March)

6. DAY Function

The DAY function extracts the day from a date.

Formula

=DAY(date)

Example

If A1 contains: 3/15/2026

Formula: =DAY(A1)

Result: 15

7. DATEDIF Function

The DATEDIF function calculates the difference between two dates.

Formula

=DATEDIF(start_date,end_date,unit)

Units You Can Use

Example: Calculate Age

If:

A1 = Birthdate
B1 = Today

Formula: =DATEDIF(A1,B1,”Y”)

Result: Person’s age in years.

Example:

Birthdate: 3/15/2000
Today: 3/15/2026

Result: 26

8. EDATE Function

The EDATE function adds or subtracts months from a date.

Formula

=EDATE(start_date, months)

Example: =EDATE(A1,3)

If A1 is: 3/15/2026

Result: 6/15/2026 (Adds 3 months)

9. WORKDAY Function

The WORKDAY function calculates a future or past working day, excluding weekends.

Formula

=WORKDAY(start_date,days)

Example: =WORKDAY(A1,10)

This adds 10 working days to the date in A1.

This is useful for:

• Project deadlines
• Work schedules
• Delivery dates

10. NETWORKDAYS Function

The NETWORKDAYS function calculates the number of working days between two dates.

Formula

=NETWORKDAYS(start_date,end_date)

Example: =NETWORKDAYS(A1,B1)

If:

A1 = March 1, 2026
B1 = March 15, 2026

Excel will count only weekdays (Mon–Fri).

This is useful for:

• Payroll
• Attendance
• Project management

Tips for Using Date and Time Functions

Here are some helpful tips when working with dates in Excel:

1. Always Use Proper Date Format

Make sure the cell is formatted as Date.

You can change this by:

Home → Number Format → Date

2. Avoid Typing Dates as Text

Incorrect: March 15 2026

Correct: 3/15/2026

Excel may treat text dates as normal text and formulas will not work.

3. Use TODAY for Automatic Updates

The TODAY() function automatically updates every day when the file is opened.

This is useful for:

• Dashboards
• Deadline tracking
• Task monitoring

Simple Example: Task Deadline Tracker

Excel will automatically calculate how many days remain.

Final Thoughts

Date and time functions in Microsoft Excel are extremely useful for managing schedules, deadlines, and data analysis. Once you understand functions like TODAY, NOW, DATE, YEAR, MONTH, DAY, and DATEDIF, you can easily perform calculations involving dates.

These functions are widely used in:

• Business reports
• Payroll systems
• Project management
• Attendance tracking
• Personal planning

By practicing these formulas regularly, you will become more efficient when working with Excel spreadsheets.
