Generally, Thais greet our new year with a traditional celebration. We are a culture with Buddhist background, so most of the emphasis is placed on wishing others to be happy and for the peaceful state of the body, the mind and the spirit.  This believe is quite different from that of the chineses who place quite a lot more emphasis on the prosperity and the wealth.  

Since this country is a hot country--in fact, the Thai new year marks the coolest days of the summer, it usually rain a little in the three days (13-15 April) of the thai New Year--most of the greeting used are those wishing the love ones for a " cool and a happy New Year"   In Thai the word "cool" represent both the coolness of the atmosphere and the calm collected state of mind.  

Thai New Year is a family holiday please be sure to send your greeting early, many thais celebrate their new year by going on vacation upcountry with their family.
