There are numerous days throughout the year celebrated as New Year's Day in the different regions of the Indian Republic. The observance is determined by whether the lunar, solar or lunisolar calendar is being followed. For those regions which follow the solar calendar, the new year falls as Chet in Punjab, Bohag Bihu in Assam, Puthandu in Tamil Nadu, Vishu in Kerala, Maha Bishuba Sankranti or Odia Nababarsa in Odisha, Poila Boishakh in Bengal and Jur Sital in the Mithila region of Bihar in the Vaishakha month of the calendar. Generally, this day falls during 14th or 15th of the month of April. Those following the lunar calendar consider the month of Chaitra (corresponding to March–April) as the first month of the year, so the new year is celebrated on the first day of this month like Ugadi in Andhra Pradesh, Telangana, Karnataka and Gudi Padwa in Maharashtra. Similarly, some regions in India consider the period between consecutive Sankarantis as one month and others take the period between consecutive Purnimas as a month. In Gujarat the new year is celebrated as the day after Diwali. As per the Hindu Calendar, it falls on Shukla Paksha Pratipada in the Hindu month of Kartik. As per the Indian Calendar based on the lunar cycle, Kartik is the first month of the year and the New Year in Gujarat falls on the first bright day of Kartik (Ekam). In other parts of India, New Year celebrations begin in the spring.
