Across all realms, days pass at the same amount of time, which allows most realms in the Astral and Edaxian Domains to use the same Standard Calendar with ease. Some realms or societies don’t use this standard calendar, however, and others may choose to use it along with another calendar of their own.
The Standard Calendar is divided into 9 months, the commonly used names of which are in order: Porcela, Mhatia, Suruka, Nilvars, Enotris, Rhaeos, Ovestin, Luzdain, & Valion. Each month has 36 days, or 6 weeks with 6 days each. Instead of the weekdays being named, the weeks themselves have names, which are as follows: Phorezo, Vynteko, Alirteo, Merenio, Larkodo, & Imaluxo. Time within a day is divided into 24 hours, which contain 60 minutes each, and a minute is 60 seconds long.
Last thing of note is the way dates are written down; the most common way is by starting with the day, then the month, and the year is written last. For example, 35th of Mhatia 3029, 35 Mhatia 3029, or 35/2/3029 would all be correct ways to write down a date. Some may also choose to write down a date in a way that includes the week, i.e. 5 Imaluxo Mhatia 3029, or 5/5/2/3029. In this manner, the number of the day in the week is written down instead of the day of the month.
