Notifications one day before Next Activity Date

Dear All,

I need to make notifications which will be sent one day before Next activity Date expire.
For Example, Next Activity Date is June 9. I need notification on June 8.
How can I configure it?

For now I tried to do in via Workflow by choosing Next Activity Date <= Next Activity Date +1 (-1) day.
It doesn’t work which means I make a mistake in configuration.

It would be really helpful to get your response.

Best regards,

Try to set t Next Activity date = “Now” + 1 day
