I figured I might as well make this a threadmarked post, just for future referencing purposes for those who don't want to go look at the wiki. As a note, these names, times, etc. are all sourced from the wiki, which is itself sourced from the Tome of Salvation and Signs of Faith sourcebook, mostly because of how vital an agreed upon calendar is for keeping track of stuff like religious festivals and the like.
------------------------------------------------------------------------------------------------------------------------
There are multiple calendars in the world, based on their own 'most important' starting dates. Kislev has a calendar dating as to when the Gospodars came thundering out of the east and took over. Bretonnia has one relating to when Gilles unified them. The Imperial Calendar goes with the year of Sigmar's coronation as Emperor being Year 0. It is to give reliable, regular, standardized dates and times to the people of the Empire. Without which everything would probably fall apart into complete confusion.
So. Some important things:
1. The year is approximately 400 days long.
2. There are twelve months, split into 32 or 33 days, with six very important festival days which like between those months.
3. The weeks are eight days long.
The Days of the Week
The exact reasoning behind each day's name is likely to have originated in pre-Empire times. Market Day, for instance, occurs on different days of the week depending where in the Empire you are, and holidays and festivals are further divided temporally by the Cults and traditions in question. There is no specific weekly religious holiday, but all join in on the festival times. These are the days in general order, keeping in mind the above noted regional differences.
- Wellentag -- "Workday"
- Aubentag -- "Levyday"
- Marktag -- "Marketday"
- Backertag -- "Bakeday"
- Bezahltag -- "Taxday"
- Konistag -- "Kingday"
- Angestag -- "Startweek"
- Festag -- "Holiday"
The Months of the Year
There are, as noted, six 'extra days', which are the special festival days, which will also be included here. As for the months themselves, their names are important, as they denote the things that often happen at those times, which you will see in the list below. Ulric, being the most dominant God in pre-Imperial and immediate post-founding times, has a month dedicated specifically to him, but obviously being the God of Winter he has influence over the season and the months it touches as well. Sigmar has a month dedicated to him as well, but before him it is speculated the month belonged to Taal.
- Nachexen -- "After-Witching"
- Jahrdrung -- "Year-Turn"
- Pflugzeit -- "Ploughtide"
- Sigmarzeit -- "Sigmartide"
- Sommerzeit -- "Summertide"
- Vorgeheim -- "Fore-Mystery"
- Nachgeheim -- "After-Mystery"
- Erntezeit -- "Harvest-Tide"
- Brauzeit -- "Brewmonth"
- Kaldezeit -- "Chillmonth"
- Ulriczeit -- "Ulric-Tide"
- Vorhexen -- "Fore-Witching"
The extra days are as follows:
- Hexenstag (Witching Day – New Year's Day)
- Mitterfruhl (Start Growth – Spring Equinox)
- Sonnstill (Sun Still – Summer Solstice)
- Geheimnistag (Day of Mystery)
- Mittherbst (Less Growth – Autumn Equinox)
- Mondstille (World Still – Winter Solstice)
Some Additional Notes:
The Imperial Calendar is based off of the dwarfs, including the six festival days, which were named differently in the Empire, and the months were renamed to more Imperial sounding ones. This helped bind the Empire and the Dwarfs in mutual understanding of time/history, which was good for relations. They also had to name the days though, as the dwarfs don't break down their months into weeks or days, and literally just call them by the numbers. This is the Old World, however, and things change, isolation happens, people in one province will likely never travel outside of it, a lot of the time. Some people, even in the Empire today, in the most isolated communities use their own versions of the calendar or ignore it completely.
If you are confused about a month, or a day, when I refer to them, please refer to this post.
