Hello, when i manually input start date and end date, i am able to create an event at google calendar,  
however, when i use the expression, it is not working anymore.

Hi @Benjamin123, Google Calendar could indeed be rejecting your time format, if everything else works. From looking at [Events: insert &nbsp;|&nbsp; Google Calendar &nbsp;|&nbsp; Google for Developers](https://developers.google.com/calendar/api/v3/reference/events/insert), Google expects RFC3339-formatted values. Values like `2022-01-11T16:59:24.058Z` worked fine for me when I tested this:

You could use the Date & Time node to reformat your timestamps, e.g. like so:
