When working with dates and times in Excel, it's common to encounter situations where you need to merge date and time values into a single cell. This can be particularly useful for tasks such as creating timestamps, logging events, or scheduling appointments. In this article, we'll explore the different methods to merge date and time in Excel, along with some practical examples and expert insights.
Understanding Date and Time in Excel
Before we dive into merging date and time, it's essential to understand how Excel stores and handles these values. In Excel, dates are stored as serial numbers, with each date represented by a unique number. For example, January 1, 1900, is represented by the serial number 1, while January 1, 2022, is represented by 44661. Time values, on the other hand, are stored as decimal fractions of a day. For instance, 12:00 PM is represented by 0.5, while 6:00 AM is represented by 0.25.
Merging Date and Time using the CONCATENATE Function
One of the simplest ways to merge date and time in Excel is by using the CONCATENATE function. This function allows you to combine two or more text strings into a single string. To merge date and time using CONCATENATE, follow these steps:
| Step | Description |
|---|---|
| 1 | Select the cell where you want to merge the date and time |
| 2 | Type the CONCATENATE function: =CONCATENATE(A2, " ", B2), assuming the date is in cell A2 and the time is in cell B2 |
| 3 | Press Enter to apply the formula |
The CONCATENATE function will merge the date and time into a single string, with a space in between. However, this method has some limitations, as it doesn't allow for automatic updates if the date or time changes.
Merging Date and Time using the TEXT Function
Another method to merge date and time in Excel is by using the TEXT function. This function converts a value to text in a specific format. To merge date and time using TEXT, follow these steps:
| Step | Description |
|---|---|
| 1 | Select the cell where you want to merge the date and time |
| 2 | Type the TEXT function: =TEXT(A2, "mm/dd/yyyy") & " " & TEXT(B2, "hh:mm AM/PM"), assuming the date is in cell A2 and the time is in cell B2 |
| 3 | Press Enter to apply the formula |
The TEXT function allows you to specify the format for both the date and time, providing more flexibility than the CONCATENATE function.
Merging Date and Time using the & Operator
Excel also provides a simple way to merge date and time using the & operator. This method is similar to CONCATENATE but uses a more concise syntax. To merge date and time using the & operator, follow these steps:
| Step | Description |
|---|---|
| 1 | Select the cell where you want to merge the date and time |
| 2 | Type the formula: =A2 & " " & B2, assuming the date is in cell A2 and the time is in cell B2 |
| 3 | Press Enter to apply the formula |
The & operator provides a quick and easy way to merge date and time, but it may not offer the same level of flexibility as the CONCATENATE or TEXT functions.
Key Points
- Merging date and time in Excel can be achieved using CONCATENATE, TEXT, or the & operator.
- Understanding how Excel stores dates and times as serial numbers and decimal fractions is crucial for accurate merging.
- The CONCATENATE function provides a simple way to merge date and time but may not allow for automatic updates.

- The & operator provides a quick and easy way to merge date and time.
Best Practices for Merging Date and Time in Excel
When merging date and time in Excel, it's essential to follow best practices to ensure accuracy and consistency. Here are some expert tips:
| Best Practice | Description |
|---|---|
| Use a consistent format | Ensure that the date and time formats are consistent throughout your worksheet. |
| Consider regional settings | Take into account the regional settings and formatting options to avoid errors. |
| Use formulas instead of manual entry | Use formulas to merge date and time instead of manual entry to ensure accuracy and automatic updates. |
