Guru Nanak Dev was the founder of Sikhism and the first of the ten revered Sikh gurus. His birth is celebrated as Gurpurab on Kartik Purnima, the full-moon day in the Kartik month of the Hindu calendar.
Mr Maurya had posted an image of Guru Nanak with a message, "Sikkhon Ke Pratham Dharm Guru, Darshnik aur Samaj Sudharak avam Shreshta Sangeetagya Guru Nanak Dev Ji Ki Jayanti par unhe Koti Koti Naman." The tweet, however, is no longer available.
His colleagues Ashutosh Tandon and Brajesh Pathak, copied the post before deleting it later.
Sorry for Guru Nanak Ji's birthday tweet. Confusion happened due to Wikipedia ( enclosed).- Sidharth Nath Singh (@SidharthNSingh) April 15, 2018

While UP Chief Minister's Twitter handle didn't post any birthday greetings, he visited Gurdwara Naka Hindola in Lucknow on Baisakhi, where he urged the youth "to draw inspiration from the sacrifice of the Sikh gurus to protect the country".
