Creating All-Day Event Using Power Automate

Base time

Select the start time value from the dynamic response output,

Source time zone

You can select the time zone according to your requirement. I have selected ‘Central Time’.

Destination time zone

You can select the time zone according to your requirement. I have selected ‘Central Time’.

Format string

You can choose patterns for your requirement. My requirement is to have the only Date and hence selected ‘Short date pattern’.

The final configuration should look below,

Step 5

Similarly, do the same steps for the End Date. The final action should look like below,

Step 6

Now look for action ‘Create Event (V4)’ under the ‘Outlook’ connector. Configure the actions accordingly.

Calendar id

Select calendar according to your requirement. Here I have chosen the default outlook calendar.

Subject

To make it unique I have selected the name of the event and submission time from dynamic form response outputs.

Start time

The outputs from the ‘converted time – Start Date’ action

End time

Here for the end time, I have to add a day since the flow starts counting from index 0. The expression here is addDays ((outputs from ‘converted time-end date’),1). below is the screen capture for reference.

Time zone

You can select any of the time zones. I have chosen ‘Central Time’.

Since our need is to create all-day events, click on ‘show advanced options’ for the action ‘Create Event (v4)’ and then select ‘All day Event’ property to Yes.

Step 7

The final flow design should look like below,

Testing

Now save the form and test it manually.

For different dates,

Outlook calendar Event,

For the same start date and end date,

Outlook Calendar Event,

Note: if you get the error:

“Your request can't be completed. The duration of an event marked as All day must be at least 24 hours.”

The above actions should resolve this issue. If you get stuck, you can refer to the attached flow package and import it to your environment to compare your design.
