Lore:Calendar

Months of the Year
The Tamrielic calendar is composed of twelve distinct months (sometimes called "Seasons" ), each approximately thirty days in length. Each month has an associated constellation, which is said to affect the traits of anyone born in that month, and each month corresponds roughly to an equal period of time in the Gregorian calendar. The months — and their real-life equivalents — are measured as follows:


    
§   
†   
‡  


Note that the constellation of The Serpent does not correspond to any one month, because The Serpent wanders randomly around the sky.

Days of the Week
A week in the Tamrielic calendar is also, as with the real-life equivalent, measured in seven days. In order, the days are:


The names of the days are mostly different corruptions of the same naming scheme we have on the English calendar, only with the exception of Middas and Loredas. Sundas, Morndas, Tirdas, Turdas and Fredas are respectively different corruptions of Sun, Moon, Tyr, Thor and Frigg, the same as the English calendar. Middas could mean the day at the middle of the week, as traditionally the deities corresponding to Wednesday (Wodanaz (Odin) / Mercury / Hermes) could not possibly be corrupted to form a "mid-" stem. It would, however, be analogous to the German word for Wednesday, "Mittwoch", and its literal English translation and synonym "midweek". Loredas is most likely taken from the Nordic languages where Saturday is called a "Bath Day" - "lördag", "lørdag," or "laurdag", in place of the Roman God Saturn, as the Vikings had a habit of bathing on Saturday.

Arena Calendar
This calendar is found in a reference sheet included with Arena.  It represents a Tamriel-ified version of the actual 1993 calendar, which was the year the game was intended to be released.

The calendar within Arena does not correspond to the one given above, as each month has 30 days. New games will begin either on the first of Morning Star or the first of Hearthfire, 3E 389.

There are several other discrepancies related to the calendar to note:
The first day of every month is a Tirdas.
In the Player's Guide, the two holidays are listed under 'Morningstar'. It is rendered 'Morning Star' in all other instances.
The month 'Hearthfire' is portrayed several different ways. The notice within a city for Tales and Tallows refers to it as 'Hearth Fire'. The Codex Scientia renders it 'Heart Fire', 'Heartfire', and 'Hearth Fire' at different times.
The Player's Guide lists North Wind's Prayer as falling on the first of Evening Star. In Arena, it falls on the 15th, as the other calendars suggest.
The Player's Guide makes no mention of Old Life Festival. This appears to be correct, however, as no holiday occurs within Arena on this date.

Daggerfall Calendar
Daggerfall's calendar was somewhat different, in that each month had 30 days, and always started on a Sundas.  This is what it looks like:

Oblivion Calendar
The Third Era ends in the year 433, as it is the year of the deaths of both the penultimate Emperor Uriel Septim VII and final Emperor Martin Septim along with the Oblivion Crisis. The game always starts on Morndas, 27th of Last Seed.

3E 433


Skyrim Calendar
The Fourth Era of Tamriel counts its first day as the day of Martin Septim's sacrifice to end the Oblivion Crisis. It is unclear as to whether this marks the final day of the Third Era, or the first day of the Fourth Era.

Unlike in Arena and in Daggerfall, no holidays were specifically given.  As such this is simply the in game calendar used with Skyrim. Note that while the game will usually start with your first day, the 17th of Last Seed, as Sundas, if you had a game loaded prior to starting your new game, the day of the week will instead be whatever it was in the game that was previously loaded.
