Semmolanghan is observed during Dasara and it held great significance during ancient times. Seemolanghan 2014 date is October 3. Seema is ‘limit or confines’ and langhan means ‘to defy or to cross.’ Earlier, villagers who were confined to a particular area were allowed to break the barriers and visit villages that were out of bounds during the other periods.
Today too people make use of the day to do things that are not done usually during other periods. Some people go on trekking to tough mountains on the day.
Seemolanghan is observed on Ashwin Shukla Paksha Dasam or the tenth day during the waxing phase of moon.
