Question details

Users need to calculate and display a default date based on a specific business-day lead time when creating a new item in a SharePoint list.

How to Set SharePoint Date Column Default Values for Business-Day Lead Times

Product: SharePoint
Device & OS: not provided
Scenario: Setting up a SharePoint list form that requires users to see a pre-calculated business-day lead time default value before saving the new item.
Observed behavior: SharePoint calculated default values using TODAY or NOW do not populate in the new item form prior to saving, failing to remind users of required lead times during data entry.

Before you start

Before modifying your SharePoint list, verify your site's regional settings to ensure correct date formats and timezone calculations, and make sure you have List Owner or Site Owner permissions to add or edit columns.

Solution 1Recommended

Use Power Apps to Display Default Dates Before Saving

Because standard SharePoint calculated columns only process after saving, customizing the form with Power Apps is the best way to display a dynamic lead time default value while the user is filling out the form.

SharePoint evaluates calculated formulas on the server side when an item is created or updated. To meet the requirement of showing the calculated business-day lead time as a default value before the user clicks save, the list form must be customized.

Customize the SharePoint Form

Navigate to your SharePoint list, click 'Integrate' on the top command bar, select 'Power Apps', and then click 'Customize forms'.

Unlock the Date Card Properties

In the Power Apps Studio, select the Date DataCard in your form. Go to the 'Advanced' tab in the right-hand properties pane and click 'Unlock to change properties'.

Set the DefaultDate Formula

Select the DatePicker control inside the card. Change its 'DefaultDate' property to your required lead time calculation. For example, to add 14 days, enter: Today() + 14.

Publish to SharePoint

Click 'File', select 'Save', and then click 'Publish to SharePoint' so users can see the new dynamic default value when creating list items.

Use Power Apps to Display Default Dates Before Saving

Pre-Save Visibility: Using Power Apps ensures the user sees the date reminder instantly during data entry, reducing scheduling errors before the item is even submitted.

Solution 2

Configure Calculated Columns for Post-Creation Lead Times

If you do not strictly require the user to see the date before saving, you can use a standard SharePoint calculated column with WEEKDAY logic to determine the business-day lead time.

Frequently Asked Questions

Why doesn't my SharePoint calculated column show a default value before saving?

SharePoint calculated columns compute their formulas on the server side during the save operation. Therefore, the result cannot be displayed dynamically in the new item form before the user hits the 'Save' button.

How do I calculate business days excluding weekends in SharePoint?

Because SharePoint does not uniformly support the standard WORKDAY function in list columns, you must use nested IF and WEEKDAY functions to evaluate the start date's day of the week and add the appropriate number of calendar days to bridge over Saturdays and Sundays.

Is there a way to show a dynamic date default in the modern SharePoint list form?

Yes, the recommended approach is to customize the modern list form using Power Apps. Within Power Apps, you can set the DefaultDate property of a date picker to instantly calculate and display a future date based on today's date.

Can I use the [Today] variable in a calculated column?

SharePoint calculated columns do not support the dynamic [Today] variable directly for ongoing real-time calculations. To use the current date at the time of item creation, use the =NOW() or =TODAY() function within the formula, but remember it evaluates at the moment of saving.
