Tumpek Landep is celebrated every Saturday of the Saniscara Kliwon Wuku Landep (every 210 days). It is derived from the word Tumpak 'close' and Landep 'sharp'. In the philosophical context means Tumpek Landep grinding the Cita (heart), Buddhi (intelligence) and Manah (mind). So people who behave according to the brightness of the spirit can with a clear conscience discern what is good and what is bad.
Tumpek Landep was originally a ceremony of purification and dedication to the various ancestral heritage as daggers, daggers, spears and so on. As a result, people call Tumpek Landep as the day of the iron. However, with the modern developments is the meaning of Tumpek Landep rather vague, and increasingly deviates from the true meaning. Today the community has even tended to Tumpek Landep to interpret as the birthday of iron. So hence the many cars, buses and motorcycles and even computers, refrigerators and guns with their Tamiang ornaments as an indication that they Tumpek Landep celebrate.
