Wan Chai"(the day of offering)
On this day, apart from preparing new dresses to wear, people will make desserts to offer to monks and to give to friends and relatives. This act of generosity is also a way to show off each family’s cooking skills.
Well-to-do families will make a large amount of desserts to give away to others. In the past it was not possible to buy desserts since everyone made their own. Nowadays, some Thais follow western traditions by buying and giving cakes to others, as it is more convenient to do so rather than cooking.
