Hello @rik0399 – thanks for writing in to us!
We have a premium extension plugin that will help you to schedule your popup to display on a specific date & time.
We would suggest checking our this extension plugin: Popup Scheduling Extension plugin
You will just need to check the Local Time box as seen here: https://share.getcloudapp.com/z8uL4JD4 This way the Schedule will be based on the users’ local time and not on the server time.
For more detailed instruction on how to use it: Scheduling — Plugin Introduction & Option Settings
On a side note, if you are looking for a feature that will do exactly like your description then we can forward this directly to our development team as a feature request/improvement for our plugin.
In case you are an existing customer then please note that you can submit them here: https://wppopupmaker.com/your-account/feature-requests/
Cheers!
