Microsoft Excel Date & Time Formulas: A Guide with Examples

Microsoft Excel provides a wide range of date and time formulas to help you manipulate and calculate dates, times, and durations. In this guide, we will explore some of the most commonly used date and time formulas in Excel and provide examples to demonstrate their application.

Current Date and Time

To display the current date, use the TODAY() function. Here's an example:

• To display the current date in a cell, simply enter "=TODAY()". Excel will automatically update the date whenever you open the workbook.

Date Functions

Excel provides several functions to manipulate dates. Here are a few examples:

• To add or subtract days from a specific date, use the DATE() function. For example, to calculate a date 7 days after June 1, 2023, enter "=DATE(2023, 6, 1) + 7".
• To extract the day, month, or year from a date, use the DAY(), MONTH(), and YEAR() functions, respectively. For instance, to extract the day from the date in cell A1, enter "=DAY(A1)".
• To determine the number of days between two dates, use the DATEDIF() function. For example, to calculate the number of days between June 1, 2023, and July 1, 2023, enter "=DATEDIF(DATE(2023, 6, 1), DATE(2023, 7, 1), "d")".

Time Functions

Excel also offers functions to manipulate time values. Here are a few examples:

• To add or subtract time from a specific time, use the TIME() function. For example, to calculate a time 2 hours and 30 minutes after 9:00 AM, enter "=TIME(9, 0, 0) + TIME(2, 30, 0)".
• To extract the hour, minute, or second from a time, use the HOUR(), MINUTE(), and SECOND() functions, respectively. For instance, to extract the hour from the time in cell A1, enter "=HOUR(A1)".
• To determine the time difference between two times, use the DURATION() function. For example, to calculate the duration between 9:00 AM and 12:30 PM, enter "=DURATION("09:00:00", "12:30:00")".

Date and Time Formatting

Excel allows you to format dates and times in various ways. To format a cell as a date or time, select the cell and use the formatting options available in the toolbar or right-click and choose "Format Cells" from the context menu. From there, you can select a date or time format that suits your needs.

Conclusion

Microsoft Excel's date and time formulas provide powerful tools for managing and calculating dates, times, and durations. By understanding and utilizing these formulas, you can efficiently handle date-related tasks and perform complex calculations. Experiment with the examples provided and explore Excel's date and time functions to enhance your data analysis and reporting capabilities.
