Daily reset at Vesper (server evening): Dailies reset, Timed Events post, Timed Bosses spawn, the Quill writes (new floors appear the evening after a Sealing), Binding upkeep ticks.
Weekly: raid lockouts, Trial windows, the Ledger, guild wars declared/settled, Mastery Tree respec window, BiS drops.
Monthly: the Reading; the Ledger of Uniques audit; Hold levies settle; Oath badges (Forsworn) expire.
Season (season, ~13 Sennights): a stratum's arc; the Ledger's bound Season; cosmetic season.
No login streaks, no lost rewards, no decay (ADR-014). Time-limited content is limited in the world's time, not the player's: a Vesper boss missed is a Vesper boss someone else killed, and the Ledger says who.
