Tòlan Calendar

The Tòlan calendar is based around the moon and tides. It consists of 13 months called “moons” of 30 days, each with two 15 day periods called “tides”. The months are simply numbered (First moon, Second moon, Third moon, etc.). The tides are named after the general weather or agricultural tasks common for them in the northern temperate zone; they are, in order: Brightening, Warming, Thawing, Flowing, Lambing, Calving, Sprouting, Budding, Flowering, Stinging, Grazing, Fattening, Haying, Winnowing, Ripening, Reaping, Milling, Smoking, Brewing, Hewing, Storing, Turning, Storming, Darkening, Freezing, Snowing.

The following graphic shows the general seasons during each month/tide.

The days are numbered One-day, Two-day, Three-day, etc. Dates are given using either the Moon or the Tide, for example the 17th day of the first month could be expressed as either Seventeen-day of First Moon, or as Two-day of Warming Tide.

Years are numbered from the supposed date of creation, so the current year would be the 7050th year since creation. Formally years are calculated by year, decade, century and era. Years them selves are named Year followed by the number of the year in that decade (Year One, Year two, year Three, etc.). The Decades and centuries are simply numbered (First Decade, Third Century, etc.). An era is 500 years long and each is named after it ends, with the current era being referred to as the current era. So the current year (7050) is: Year ten of the 4th decade of the 1st century of the current era.

The eras before the current one are named for some prominent event or characteristic, though these names are not universally agreed upon, and different areas will use different era names. This lack of uniformity in the names of the eras causes no end of difficulty in historical research, etc., and so in scholarly circles the eras are also numbered (First Age, Second Age, etc.). By this usage the current era is the 14th age.

Note. The Tòlan calendar is 390 days long and published calendar for Cerilia (or at least the one on Birthright.net) is only 388 days long. I went with the 390 days because I wanted the calendar to be different, but there really was no other arrangement of months, etc. (12 months of 32 days & 4 intercalary days) that works for 388 days.


The seasons are defined by Wikipedia as follows:

Early spring (Prevernal): Deciduous tree buds begin to swell. Migrating birds fly from winter to summer habitats.

Spring (Vernal): Tree buds burst into leaves. Birds establish territories and begin mating and nesting.

Summer (Estival): Trees in full leaf. Birds hatch and raise offspring.

Late summer (Serotinal): Deciduous leaves begin to change color. Young birds reach maturity and join other adult birds preparing for autumn migration.

Autumn (Autumnal): Tree leaves in full color then turn brown and fall to the ground. Birds migrate back to wintering areas.

Winter (Hibernal): Deciduous trees are bare and fallen leaves begin to decay. Migrating birds settled in winter habitats.

Hot: Average monthly precipitation less than 60 mm (2.4”), and average daily temperatures over 30°C (86 °F).

Wet: Average monthly precipitation between 60 mm (2.4”) and 100 mm (4”).

Monsoon: Average monthly precipitation over 100mm (4”).

Dry: Average monthly precipitation less than 60 mm (2.4”).
