As a 5StarTeacher, you are in control of when your available Sessions should automatically expire when they remain "unbooked". That's why created the" Session Expiry Term". This allows you to automatically set or change the expiry date and time of all of your Available Sessions at once.

The Session's Booking Expiry Date and Time is the date and time at which an unbooked Session expires automatically. You can set your Session Expiry Term to 2 hours, 4 hours, 12 hours, 24 hours or 48 hours before the start of every Session. Currently, each month you can change this setting only 3 times.

Why is this so?
This is so that Students can rely on booking Sessions with you. Suppose you had set your Session Expiry Term at "2 hours", meaning your Available Sessions would expire 2 hours before the start date and time of those Sessions, and you changed it to 48 hours, all of a sudden, all your Sessions within the next 48 hours would then expire.

There are benefits for the Teachers too.
Suppose it's Friday but something unforeseen has come up for the weekend e.g. the babysitter has fallen ill and you need to stand in. You can then set your Session Expiry Term to 48 hours and all your "Available" Sessions will automatically expire. Note that "Booked" Sessions will not go away, you do need to show up for those. If that were not possible as well, you can choose to cancel them. See cancelling Sessions in the FAQ section to learn more.
