No, it’s not currently possible to adjust your site’s billing or auto-renewal date.
To check your site's current billing date:
- In the Home Menu, click Settings, click Billing & Account, and then click Billing.
- Under Subscriptions, click Website.
- Your next renewal/billing date is listed under Next Payment. This can't be edited.
It's possible to disable auto-renewal and reactivate it on the day that you'd like to be charged, however, keep in mind that turning off auto-renewal will cause your site to expire on the billing date, which means that your site will be taken offline until you reactivate it.
