Which fare codes need a Saturday night stay

Are the details of which fare code needs a Saturday night stay listed anywhere? I just looked in the fare codes section and I could not see it.

The advance purchase requires for each fare code would also be useful.

Thanks

Also the specific question is does an L class fare require a Saturday night stay.

For UK originating flights, all fares except the full-fare, fully flexible require a saturday night stay. (ie: Y,W,J) Economy fares do not generally require any advance purchase period, although PE and Upper fares normally require some form of advance purchase, aside from the fully flexible versions.

ISTBC but I think the reward tickets G,T,U do not require a Saturday night.
