In another thousand years it will start occurring in May. Now a days the Spring Equinox occurs on 20 / 21 March, but Vaisakhi on 13 / 14 April. According to Surya Siddhantic calculations Vaisakhi occurred on the day of the Spring Equinox in 532 CEi.

The problem with the solar part is that Vaisakhi has shifted in relation to seasons. The Bikarami Calendar is lunisolar, which means its one part is solar according to which all Sangrands (sankrantis), the first day of the month, are decided and the other part is lunar which determines tithis (sudis and vadis) according to which dates of all gurpurbs are determined. Having been linked with the Bikarami Samvat it had the same shortcomings as those in the Bikarami Samvat. Its tithis (sudis / vadis – lunar dates), sankrantis (sangrands – beginning of the solar months) were the same. Nanakshahi Samvat that had been in use was nothing but the change in name of the Bikarami Samvat. Dr Bhai Vir Singh was perhaps the only scholar who used Nanakshahi Samvat as an element of date.

Then some Punjabi Jantri (almanac) publishers started giving the Nanakshahi Samvat also in their Jantris. The Sikhs followed the Bikarami calendar to all intents and purposes until the early 20th century. Hindus have their Bikarami, and Saka calendars, the Christians have the Gregorian Calendar (which these days is called Common Era), Muslims have the Hijri calendar, even Bahais, whose faith started only in the beginning of 19th century having now a population of 5 million all over the world, have a calendar of their own. For this reason all major nations of the world evolved their own calendars. The religious festivals, celebrations, the sowing season, the harvest season, recording of dates of events, and planning for the future are all related to calendars. In this article these changes and why they were necessary are discussed.Ĭalendars are an important part of the culture of a nation. The changes were recommended by the Calendar Reform Committee under the aegis of the Institute of Sikh Studies, Chandigarh. Shromani Gurdwara Parbandhak Committee has decided to implement the new Reformed Nanakshahi Calendar from 1999 CE.
