Semmolanghan is observed during Dasara and it held great significance during ancient times. Seemolanghan 2017 date is September 30. 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. Simolanghan Ritual during Vijayadasami is famous in some temples in Maharashtra.
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 Dasami or the tenth day during the waxing phase of moon.
