Mastering date formatting in Google Sheets is crucial for anyone who works with time-based information, from students and educators to businesses and researchers.
Whether you need to present dates in a specific format for reports, sort data chronologically, or perform calculations involving dates, understanding how to format dates effectively is paramount. This comprehensive guide will delve into the intricacies of date formatting in Google Sheets, empowering you to harness the full potential of this essential spreadsheet function.
Understanding Date Formats in Google Sheets
Google Sheets recognizes dates as numerical values, representing the number of days that have elapsed since a specific reference point. By default, dates are displayed in a user-friendly format, but you can customize the appearance to suit your needs. The key to formatting dates lies in using specific codes and symbols that dictate how the date is represented.
Date Format Codes
Google Sheets uses a system of date format codes to control the display of dates. These codes are enclosed within double quotes (“) and can be inserted directly into a cell’s formatting settings. Here are some common date format codes:
- d: Day of the month (01-31)
- m: Month (01-12)
- y: Year (two digits)
- yyyy: Year (four digits)
- M: Month name (January-December)
- MMMM: Full month name (January-December)
- h: Hour (1-12, AM/PM)
- H: Hour (00-23)
- m: Minute (00-59)
- s: Second (00-59)
Example Date Formats
Let’s illustrate how these codes work with some examples:
| Date Format Code | Example | Output |
|---|---|---|
| “mm/dd/yyyy” | 01/15/2024 | 01/15/2024 |
| “dddd, MMMM dd, yyyy” | 01/15/2024 | Monday, January 15, 2024 |
| “yyyy-MM-dd” | 2024-01-15 | 2024-01-15 |
Formatting Dates in Google Sheets

Then, click on the “Format” menu and choose “Number.” In the Number format dialog box, select “Date” from the Category dropdown list. Choose the desired date format from the list of options or create a custom format using the format codes described earlier.
2. Applying a Predefined Date Format
Google Sheets offers a variety of predefined date formats that you can apply directly to your cells. Click on the cell or range of cells, then click on the “Format” menu and choose “Number.” Select “Date” from the Category dropdown list, and you’ll see a list of common date formats.

Working with Dates in Formulas
Google Sheets provides a wealth of functions for working with dates in formulas. Here are some essential date functions:
1. TODAY()
The TODAY() function returns the current date. For example, `=TODAY()` will display the current date in your spreadsheet.
2. NOW()
The NOW() function returns the current date and time. For example, `=NOW()` will display the current date and time in your spreadsheet.
3. DATE()
The DATE() function creates a date from year, month, and day arguments. For example, `=DATE(2024, 1, 15)` will create a date representing January 15, 2024.
4. TIME()
The TIME() function creates a time from hour, minute, and second arguments. For example, `=TIME(10, 30, 0)` will create a time representing 10:30 AM.
5. DAY(), MONTH(), YEAR()
These functions extract the day, month, and year from a date value. For example, `=DAY(A1)` will return the day of the month from the cell A1.
6. DATEDIF()
The DATEDIF() function calculates the difference between two dates in years, months, or days. For example, `=DATEDIF(A1, B1, “y”)` will return the number of years between the dates in cells A1 and B1. (See Also: Google Sheets How to Name a Column? Easy Step Guide)
Advanced Date Formatting Techniques
Beyond the basics, Google Sheets offers advanced date formatting techniques to handle complex scenarios:
1. Formatting Based on Conditions
You can apply different date formats based on specific conditions using conditional formatting. Select the cells containing the dates, click on the “Format” menu, and choose “Conditional formatting.” Create a rule that applies a specific date format to cells that meet a certain condition, such as dates within a particular range or dates that have a specific value.
2. Text to Date Conversion
Google Sheets can convert text strings representing dates into actual date values. Use the DATEVALUE() function to achieve this. For example, `=DATEVALUE(“01/15/2024”)` will convert the text “01/15/2024” into a date value.
3. Date Serial Numbers
Google Sheets represents dates as serial numbers, where each day is assigned a unique number. This allows for precise date calculations and comparisons. You can use the DATEVALUE() function to convert a date string into its corresponding serial number.
