Background: Time in Umbria

This is the calendar associated with the Common Tongue in Umbria, based largely on the cycles which have marked time for rural folk for time immemorial.  Other races (Elves, Dwarves, etc.) have their own calendars, as do certain distinct human cultures/elites.

The year is divided into 16 months.  One month is measured by the phases of the primary moon, Luna, each month numbering 21 days.  Each month is divided into 3 weeks of 7 days (known literally, as 'sevendays') each and each season (Spring, Summer, Autumn and Winter) is made up of 4 months.  Between each 4 month season is a seven day period, at the centre of which lie the solstices (for Summer and Winter) and equinoxes (for Spring and Autumn).  Of course because these solar 'sevendays' do not correspond with Luna's phases, the primary moon is seldom in perfect alignment with the months.  Known as Deepwinter, Birthspring, Midsummer and Fallbrew, these sevendays are regarded as holidays in most civilized lands, culminating in the solstice celebrations of Sun Still (Midsummer) and World Still (Deepwinter) and the equinox celebrations of Greengrass (Birthspring) and Highharvestide (Fallbrew).
