The Yipeng or Dueanyi Festival comes from the word yi in Lanna referring to the second lunar month and peng means full moon night. Thus, yipeng refers to the full moon night/day of the second lunar month, which falls on the full moon period of the 12th month of Central Thailand. The Lanna calendar is the lunar calendar, like the Chinese calendar. Therefore, it is two months ahead of the first month in the Central Thai Calendar.

The Sadokhro ritual is an ancient custom which nowadays is held in only a few places. This ritual is meant to cast out diseases or accidents that happen to occur to a person which is considered serious and could cause one to die. Sometimes, it is included as part of some other important ceremonies like a birthday and New Year to ensure that all will be well for that year and that no undesirable incident or bad luck will occur in the coming year.
There are a few ways to perform the rite. One is to light a candle to send away bad luck, another is called song-puthaen-yathaen. The Suepchata or life extension ceremony is also a way to rid one of bad luck. Another old time method of dispelling bad things known as Sadonophakhro is also acceptable.
The tradition of Suep Chata Mueang or Extension of the Citys life is an ancient Lanna custom held to boost the spirit and morale of the city and the people to ensure the wellbeing and long life of the city establishment.

That is when the city faces turmoil due to war and starvation, which is the sign of the citys fate declining. The other occasion is when the city is peaceful.
Since the entering of Buddhism into the land of Lanna long ago, it has become well established and gained permanent ground and its teaching has firmly influenced the peoples beliefs and actions. Theravada Buddhism in particular gives importance to paying respect to the relics of the Lord Buddha and several Lanna kings adopted the practice of bringing relics from distant lands to be housed in a chedi of their cities or towns. This tradition has bestowed dignity and power on the township system in Lanna.
