Calendar

Weekdays

In the Floraverse, a week is divided in seven days: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.

Topside's sky

The Topside world has three moons.

The main moon, simply called The Moon is always visible in the night's sky. The two others are not always visible.

When the second moon, Lil Luna, also commonly called Luna, is visible in the sky on a Monday, that day is called a Double Monday.

The third moon, Small Selene, commonly called Selene, may be visible along the two others every three months. That day is commonly refered as a Triple Monday, and can happen any day on the week.

Months

The year, containing 365 or 366 days, is commonly divided into twelve months, all named after an animal.

Name Animal Duration in days
Rath Rat 31
Oxoth Ox 28 or 29
Tigoth Tiger 31
Raboth Rabbit 30
Drath Dragon 31
Snakoth Snake 30
Horth Horse 31
Goath Goat 31
Monmonth Monkey 30
Roosoth Rooster 31
Doth Dog 30
Pigoth Pig 31

Era

At the time when Seeds: a mini story happens, most of Owel is in the year 633 of their era. The event serving as the starting reference for that era is not known.
Mew-York, unlike the rest of Owel, is currently in the year 352. The event marking that new era could be their independance, probably from Kadath, after the whole area surrounding Mew-York was made devoid of magic.
Since almost no reference was released about the other continents of Topside, it is not known if they follow the same era for counting years.
The current year in the Blackjack Isles is not know either.
