Hi there 👋 we refer to that billing date as the Subscription's billing cycle anchor. This section walks through the different options availble for updating that for an existing Subscription, but let me know if there is anything in there that is unclear:

Those approaches focus on making changes to the Subscription directly, while it is a bit more tedious, you can also do that with Subscription Schedules and they give you a bit more flexibility:
