Wai is traditional Thai greeting, and is generally offered first by person who is younger or lower in social status
and position. Respects for elderly (by age, position, monks, or certain professions) is Thai mores. As with other
Asian cultures, respect towards ancestors is an essential part of Thai spiritual practice. Thais have strong sense
of social hierarchy, reflecting in many classes of honorifics. Seniority is paramount in Thai culture. Elders have
by tradition ruled in family decisions or ceremonies. Older siblings have duties to younger ones.
Thais have a strong sense of hospitality and generosity. Taboos in Thailand include touching someone's head
or pointing with the feet, as the head is considered the most sacred and the foot the lowest part of the body.
Thailand's national religion, Theravada Buddhism, is central to modern Thai identity. Thai Buddhism has evolved
over time to include many regional beliefs originating from Hinduism, animism, as well as ancestor worship.
The official calendar in Thailand is based on the Eastern version of the Buddhist Era (BE).
