Stripe

In development mode, the subscription start date is the one of the customer "Current simulation time" (instead of the date of creation of the subscription). This can be changed by editing the customer: https://dashboard.stripe.com/test/customers -> Select the customer -> "Advance time".

Advancing time allows simulating time advancing very quickly to test events such as arriving to the expiration date.
