As Siderea is set on a pseudo-earth planet, Dorei, the planet-sun relationship is the same as on Earth. Thus, the cycles of day and night and the seasons work in the same way.
Sidereals count their years starting from the Age of the Sunkillers. Currently, the year is 1834, making it 1834 years since the Sun was assassinated by cursed ones and the subsequent massacre.
Sidereal months are named after the monikers of the first twelve Suns, in old Sidereal. They correspond to Earth months as follows:
- Oculus (January)
- Natura (February)
- Tempus (March)
- Vox (April)
- Remedium (May)
- Genesis (June)
- Animus (July)
- Dolus (August)
- Bestia (September)
- Virtus (October)
- Somnium (November)
- Phasma (December)
Sidereal weekdays are named after the planets of the known universe, mirroring the orbital system with the addition of the Moon:
- Sunsday (Sunday)
- Helsday (Monday)
- Ludsday (Tuesday)
- Dorsday (Wednesday)
- Vomsday (Thursday)
- Kilsday (Friday)
- Moonsday (Saturday)
Celebrations in Siderea are modest. The way each person leads their every day life is in and of itself a celebration of Sidereal tradition and culture, making grand celebrations of it unnecessary. Traditional food is made, celebrational garments are worn, special songs are sang, and that is as extravagant as Sidereal holidays get.
The most elaborate celebration is the Sidereal New Year. It is celebrated on the day of the summer solstice, which brings the most hours of sunlight in a year. It usually falls around the 21st day of Genesis, and is a half-work day, with the second half free for celebration with family and compatriots.
The winter solstice, with the least hours of sunlight in a year, is a day of mourning for those fallen in the Age of the Sunkillers. It is a work day, during which everyone is required to wear black and stay in silence, speaking only if absolutely necessary.
The autumnal and vernal equinoxes, where night and day are believed to be equal, are celebrations of balance, of the Sun’s power to keep the darkness of the Void at bay, and of the contributions each and every Sidereal makes to uphold the delicate cosmic order of things. It is a work day, and everyone wears traditional garments. The Sun will address their people with a special speech at the end of the day.
The Lunar eclipses are cause for talk and excitement, but no special celebrations are held.
The Solar eclipses, on the other hand, call for a curfew, during which nobody is allowed to step outside until the total eclipse passes. This is done out of caution, as the sun’s light is believed to be dangerous during the eclipse. However, there is also a superstitious fear of seeing their sun blacked out that keeps people inside, although no Sidereal would openly admit to such childish fear of the astronomical event.
