Songkran, Loy Krathong and major festivals
Two festivals stand out. **Songkran** (Thai New Year, mid-April) is the famous nationwide water festival — expect days of friendly water-throwing in the streets; protect your phone, and note many businesses close and roads are more dangerous due to holiday traffic. **Loy Krathong** (full moon of the twelfth lunar month, usually November) sees people float decorated banana-leaf 'krathong' on water at night; in the north (Chiang Mai) it coincides with the Yi Peng sky-lantern releases. Other key dates include Chinese New Year and several Buddhist holy days, on which alcohol sales are restricted nationwide.
