Twilight

From SA Mafia Wiki

Twilight is a period of time after the execution has occurred in which players may continue to talk in thread, but no votes may be cast and no day actions will be counted. Twilight exists at the mod's discretion, and generally lasts for no more than an hour after the execution.

Depending on the mod, cardflip may take place before or after the twilight phase.

Twilight can be helpful for the town as it allows them to discuss possible night actions as a result of the day's cardflip(s). Or it can just be an opportunity to gloat/moan.
