The Tempestian calendar (also known as the Tranquillitan calendar) has become the global standard for timekeeping everywhere except the Empire and a few other holdouts. Even those holdouts tend to use the Tempestian calendar for international business, something which causes no end of headaches for the rest of the world.
Unlike the Imperial calendar, the Tempestian calendar doesn’t have standardized month lengths, with months instead having old, often seemingly-random lengths based on old history long lost. Many in the Empire argue that this makes it poor timekeeping in comparison to the more consistent Imperial calendar, though that the Tempestian calendar adds up to 365 days without ‘cheating’ is the most common rebuttal.
In the Tempestian calendar, rather than months and days, there are ‘phases’ and ‘cycles’, with phases being named for steps of the alchemical process– at the time the calendar was created, one of the primary methods of scientific progress in ancient Pluvia. Years are counted in years AP, or anno pax: the time since the conclusion of the Ventus-Pluvian War.
The phases of the Tempestian Calendar as follows:
- Phase of Calcination (31 days)
- Phase of Dissolution (28 days)
- Phase of Separation (31 days)
- Phase of Conjunction (30 days)
- Phase of Putrefaction (31 days)
- Phase of Congelation (30 days)
- Phase of Cibation (31 days)
- Phase of Sublimation (31 days)
- Phase of Fermentation (30 days)
- Phase of Exaltation (31 days)
- Phase of Multiplication (30 days)
- Phase of Projection (31 days)Dates in the Tempestian calendar are formatted as the [c]th Cycle of [p]. For example, the sixth day of the ninth month would be the Sixth Cycle of Fermentation.
