Sinhalese New Year, generally known as Aluth Avurudda (Sinhala: අලුත් අවුරුද්ද) in Sri Lanka, is a Sri Lankan holiday that celebrates the traditional New Year of the Sinhalese people of Sri Lanka. It is a major anniversary celebrated by not only the Sinhalese people but by most Sri Lankans. The timing of the Sinhala New Year coincides with the new year celebrations of many traditional calendars of South and Southeast Asia. The festival has close semblance to the Tamil New year and other South and Southeast Asian New Years. It is a public holiday in Sri Lanka (02 Public Holidays - Normally Shops Close for Around One Week Following the New Year). It is generally celebrated on 13 April or 14 April and traditionally begins at the sighting of the new moon.
