You can update your delivery and pickup hours separately to show when your restaurant is open for business on Grubhub. This allows you to be open for pick-up or delivery to align with your schedule, and remain open for pick-up if you are not doing delivery during all hours of operation and holiday hours as well.
To add holiday hours on GrubHub:
1. Log in to your GrubHub merchant account.
2. Select Hours from the left sidebar on your desktop and to update your holiday hours, click on the pencil icon.
3. Enter the open and close times for each day. To be closed all day, uncheck the box for each day.
