Streamlining your workflow in Excel 365 often involves automating repetitive tasks, and adding a date and time picker can significantly enhance your productivity. This nifty feature allows you to insert dates and times quickly and accurately, reducing manual errors. Let's delve into how to add a date and time picker in Excel 365.

Before we dive into the process, ensure you're using the latest version of Excel 365. The date and time picker feature is a recent addition, and older versions may not support it. Now, let's explore the two main methods to add a date and time picker in Excel 365.

Using the Built-in Date and Time Picker
Excel 365 comes with a built-in date and time picker that's easy to use and integrates seamlessly with your workflow. Here's how to access and use it:

First, click on the cell where you want to insert the date or time. Then, instead of typing the date manually, click on the small calendar icon that appears in the bottom-right corner of the cell. This will open the date and time picker.
Selecting a Date

To choose a date, simply click on the desired date in the calendar. The selected date will automatically appear in the cell. You can also use the arrow keys to navigate through the calendar or type in the date manually in the 'Date' field at the top.
To adjust the view of the calendar, click on the 'Month', 'Year', or 'Decade' buttons. You can also switch between the calendar and a list view by clicking on the 'List' button. Once you've selected your date, click 'OK' to confirm.
Selecting a Time

To insert a time, click on the 'Time' field at the top of the date and time picker. A drop-down menu will appear, allowing you to choose the hour and minute. You can also type in the time manually. Once you've selected your time, click 'OK' to confirm.
If you need to insert both a date and a time, you can do so in a single step. Simply select the date first, then choose the time from the drop-down menu. The date and time will be inserted into the cell in the format you've specified in your Excel settings.
Using a Data Validation List for Date and Time Picker

Another method to create a date and time picker in Excel 365 involves using a data validation list. This method is useful when you want to restrict the user's input to a specific range of dates or times. Here's how to do it:
First, create a list of dates or times in a separate column. You can do this manually or use a formula to generate the list. For example, to create a list of dates from today to one year from now, you can use the following formula in cell A2 and drag it down to copy it for the rest of the list:




















TODAY() + (ROW() - 1)
Once you've created your list, select the cell where you want to insert the date or time picker. Then, go to the 'Data' tab in the Excel ribbon and click on 'Data Validation'. In the 'Settings' tab, under 'Allow', select 'List'. In the 'Source' field, enter the range of cells containing your list. Click 'OK' to confirm.
Using the List
Now, whenever you click on the cell with the data validation list, a drop-down arrow will appear. Clicking on this arrow will display your list of dates or times. Simply select the desired date or time from the list, and it will be inserted into the cell.
This method not only saves time but also ensures that the user's input is always within the specified range, preventing errors and inconsistencies in your data.
Customizing the Data Validation List
You can customize the data validation list to suit your needs. For example, you can change the title of the list, add a input message, or restrict the list to a specific number of items. To do this, go back to the 'Data Validation' dialog box and adjust the settings in the 'Input Message' and 'Error Alert' tabs.
You can also use formulas to generate dynamic lists based on other criteria in your workbook. For example, you can create a list of dates that are within a certain number of days from today, or a list of times that are within a specific range.
Incorporating date and time pickers into your Excel 365 workflow can significantly improve your productivity and reduce errors. Whether you're using the built-in date and time picker or creating a data validation list, these tools can help you streamline your tasks and keep your data accurate and consistent. So, go ahead and give them a try – your future self will thank you!
