One of the chapters in the forthcoming ‘The Realm of Sommerlund’ supplement for LWAG is the Calendar of Sommerlund. This covers all the Sommlending week days, months, seasons, feast-days etc. Here’s a summary:

One day = 24 hours
One week = 7 days
One month = 30 days
One year = 360 days

SOMMLENDING DAYS OF THE WEEK
Sunday = Kaidag
Monday = Mentdag
Tuesday = Liodag
Wednesday = Midvoka
Thursday = Urkadag
Friday = Fehdag
Saturday = Ishdag

SOMMLENDING SEASONS & MONTHS
Spring = FEHANGOR
April = Berkano
May = Perthro
June = Jera

Summer = SOLANGOR
July = Hagalas
August = Gebo
September = Raidho

Autumn (Fall) = HESTANGOR
October = Ansus
November = Uras
December = Othala

Winter = KALTANGOR
January = Ingwas
February = Mannas
March = Ehwas

SOMMLENDING FESTIVAL DAYS
Fehmarn = First Day of Spring (Berkano 1st)
Maesmarn = Mid-Summer’s Day (Gebo 15th)
Folmarn = Mid-Autumn (Uras 15th)
Kaltmarn = Mid-Winter’s Day (Mannas 15th)

Unlike our familiar Earth year, each New Year in Magnamund begins on the First Day of Spring. The Earth equivalent, i.e., the first day of a new Sommlending year, is April 1st. Therefore, I propose we celebrate our first Feast of Fehmarn on April 1, 2015.

Using the above summary, you’ll be able to work out your own Sommlending birthday. Mine is February 12th, which is Mannas 12th on the Sommlending Calendar. If your birthday falls outside of the Sommlending calendar (i.e. on Jan 31, Mar 31, May 31, Jul 31, Aug 31, Oct 31, or Dec 31, then I suggest you carry it over to the 1st of the following month. For example, if your birthday is Jan 31, the Sommlending equivalent would be Mannas 1st (Feb 1st).
