Are you struggling to change the time format in Microsoft Excel to suit your needs? Whether you're preparing data for a presentation, managing employee schedules, or just organizing your daily planner, having your time display correctly is crucial. In this blog post, we'll explore five simple yet effective tips to change time formats in Excel, making your spreadsheet tasks easier and your data clearer.
Understanding Excel’s Time Format
Before diving into the tips, it’s essential to understand how Excel handles time:
- Time in Excel is stored as a decimal number representing the fraction of a day.
- The default time format might not always suit your data’s context, hence the need for custom formats.
- Customizing time formats can reveal time in hours, minutes, seconds, or even AM/PM indicators.
Tip 1: Changing Time Format Using the Format Cells Dialog
One of the most straightforward methods to change time format in Excel involves using the Format Cells dialog:
- Select the cells containing the time you wish to format.
- Right-click and choose ‘Format Cells’, or use the keyboard shortcut Ctrl+1.
- In the dialog box that opens, go to the ‘Number’ tab.
- Under ‘Category’, choose ‘Time’.
- Select your preferred time format from the list. You can also create custom formats here if needed.
- Click ‘OK’ to apply the changes.
💡 Note: If your time isn't formatted correctly, Excel might not recognize it as time. Check for extra spaces or incorrect punctuation.
Tip 2: Using Custom Time Formats
If the predefined time formats don’t meet your needs, Excel allows you to create custom ones:
- Follow the steps to open the ‘Format Cells’ dialog.
- Instead of selecting ‘Time’, click on ‘Custom’.
- In the ‘Type’ box, you can enter a custom time format:
- Use ‘h:mm AM/PM’ for 12-hour clock time with AM/PM indicator.
- Use ‘HH:MM:SS’ for a 24-hour time format.
- Add text like ‘Time: ’ before the format if needed.
- After typing in your desired format, click ‘OK’.
Tip 3: Incorporating Time in Date Formats
Often, you might need to include time with dates. Here’s how you can do it:
- Select the cells with your dates or times.
- Open ‘Format Cells’ as described above.
- Choose ‘Custom’ under the ‘Number’ tab.
- In the ‘Type’ field, enter a date format followed by a time format, e.g., ‘MM/DD/YYYY HH:MM’.
- Confirm your settings by clicking ‘OK’.
⏰ Note: Ensure that the date and time are in the same cell to format them together correctly.
Tip 4: Handling Fractions of Time
Excel can also handle fractions of time, useful for tracking work hours or project durations:
- Enter time directly in the cell, e.g., 2:30 for two hours and thirty minutes.
- To format, use ‘Format Cells’, choose ‘Time’, then select a format with hours and minutes.
- If you want to display time as a fraction, use a custom format like ‘[h]:mm:ss’ for hours, minutes, and seconds.
Tip 5: Using Formulas for Time Manipulation
Excel isn’t just for formatting; you can use formulas to manipulate time as well:
- To add or subtract time, simply use the ‘+’ or ‘-’ operators with time values.
- Use the TEXT function to format time on the fly:
Function Description =TEXT(A1, “HH:MM:SS”) Converts a time in cell A1 to HH:MM:SS format. 
- The TIME function can be used to create specific times:
- =TIME(2,30,0) returns 2:30 AM.
Using these tips, you can now effortlessly change how time is displayed in Excel, ensuring that your spreadsheets serve your needs precisely. Remember, understanding how Excel treats time as a number can unlock even more possibilities for data analysis and presentation.
With these steps, you've not only learned how to modify time formats but also how to use Excel's capabilities to your advantage. Whether you're tracking project times, converting time zones, or presenting data, these tools ensure that your time data looks the way you want, making your work more efficient and your spreadsheets clearer.
How can I quickly change all time formats in an Excel sheet?

+
Yes, use the formula ‘=A1+TIME(5,0,0)’ where A1 is the original time and the TIME function adds 5 hours to convert to another time zone.
What if my time appears as a number like 0.04167?
+
This means Excel recognizes the time as a fraction of a day. You can change the format using the ‘Format Cells’ dialog or use a custom format to display it properly.
Can I calculate duration between two times?
+
Yes, simply subtract the start time from the end time. If your end time is in cell A2 and start time in A1, use ‘=A2-A1’ to get the duration.
