The Nanakshahi Sikhism Calendar

The Nanakshahi calendar is used only by Sikhs. It was created by Pal Singh Purewal to establish fixed dates for observing important Sikh commemorative events related to the history of the Sikh gurus which took place in ancient Punjab (North India) including:

  • Birth (prakash - the manifestation of light)
  • Inauguration as Guru (guru gadee - enthronement)
  • Martyrdom or death (jyoti jot - the merging of manifest light into divine light)

Prior to the use of the Nanakshahi calendar, the date on which a commemorative Sikh event would be observed corresponded to a solar calendar based on lunar cycles which changed with each succeeding year. The Shiromani Gurdwara Prabhandak Committee (SGPC), the governing office of Sikhism located in the Punjab, adopted the Nanakshahi calendar in 1988, mandating its use and spurring controversy among Sikhs accustomed to tradition.

The Nanakshahi is a solar based calendar which begins in the middle of March. The Nanakshahi calendar year 0001 begins with the year of Guru Nanak's birth in 1469 AD. The New Year begins on March 14th.

The Nanakshahi Calendar was amended in 2003 and again in 2010, on the Nanakshahi New Year 542 by the SGPC of India to accommodate traditional full moon festivals causing great controversy and many potential problems with dates and seasons shifting especially between differing East and West calendars. Each subsequent year has amendments to original fixed dating of the 2003 Nanakshahi calendar.

The Twelve Months of the Guru Granth Sahib

The names of the Nanakshahi months correspond to those in the hymns of Gurbani which appear numerous times throughout the scripture of the Guru Granth Sahib.

Commemorative Dates Observed in Sikhism

The events and dates of The Nanakshahi calendar entries given may differ by months, or even years, from original historical records such as the Vikram Samvat (SV), or Bikram Sambat (BK), calendar based on lunar cycle dating. Some of the names of the Nanakshahi months are like those of the Hindu Calendar. Even with the creation of the Nanakshahi calendar, the dates observed in Western parts of the world sometimes vary. This may be due to the confusion over conversion of calendar months from Vikram Samvat to Julian to Gregorian to Nanakshahi, differences between time zones of Punjab and other parts of the world, or other factors such as convenience and tradition. A date which falls close to a holiday observed in a particular country or a weekend may be celebrated when people are able to take time off from work. Celebrations are sometimes staggered over a period of weeks, or even a couple of months, so that festivities in different locations can take place without over lapping. Commemorative festivities in Sikhism, such as gurpurab, focus on events having to do with the ten gurus, their families, and Guru Granth Sahib:
