If you would like to change the online ordering hour for either pick up and/or delivery, you can do so by selecting your Settings & Configurations Block and then choose the Online Menu Block. Scroll to the bottom of the page, where you will see your Pick Up and Delivery functionality:
In the photo above, you will see the hours set for each individual day. Here, you can manually manage the online ordering hours for each day. For example, if you would like for customers to be able to place orders for pick up between the hours of 12:00am - 10:00pm on Saturdays, you would set your Open time on Saturday to 12:00am and your Close time on Saturday to 10:00pm.
If the hours are the same for every day, you can Set For All. Additionally, you can Clear Time, which will clear all time selections so that you can start with a clean slate.
