Convert Date to String

Hi @AnnaLee 

What is the source of the Date? Variable or List Item

What are you saving the Date into? Variable or List Item

Example: Create a DateTime Variable

Using a Set Workflow Variable action, we create a DateTime Type variable and set it to the current Date

Using the Datetime variable in an Email Body

Add a Send Email action, place the cursor in the Message Body.

Click Advance Lookup, select the "dt_DateNow" variable and click the format icon

Using the Format option, choose how to format the value.  

Lastly, click the Insert button. 

You can format both DateTime type current item or variable.
