You can add a trading hours adjustment if you are opening earlier or closing laterthan your regular trading hours. 

An example may be that you are closing later for Valentine's Day. You can extend your hours on a specific day.

1. Go to bookings > special Dates > + add special dates. 

Ensure you toggle the "trading hour adjustments on"

You can do a single date or recurring. If it is recurring, then you can permanently change your trading hours in your settings.

Ensure you extended trading hours start when your current trading hours end. For example you could close at 5 pm. You can start your extended training hours from 5 pm to 9 pm.
