It was Military Secretary to the President, Major General Anil Khosla, inviting 71-year-old Kovind and his wife Savita to the Rashtrapati Bhavan, where President Pranab Mukherjee was waiting for them in the study.
The two leaders then went to the grand Rashtrapati Bhavan forecourt where they were escorted to the saluting dais. Mr Mukherjee took the last salute of the President's Bodyguard (PBG) with President-elect Kovind standing to his left.
He and his successor drove down Raisina Hill to the Central Hall of the Parliament in a black limousine, with Mr Mukherjee in the right and Kovind on the left.
Escorting them was a grand equestrian procession by the PBG, dressed in white ceremonial uniforms and blue turbans with gold ornamental work.
The road from Rashtrapati Bhavan to Parliament was lined with 1,000 jawans from all three services of the armed forces offering the traditional 'hazaar salaam' to the president - the supreme commander of the defence forces.
After the oath ceremony, President Kovind met leaders in Central Hall before leaving for the Rashtrapati Bhavan in the presidential limousine, this time with Mr Mukherjee in the left and India's new president on the right.
The skies opened up as the procession made its way from Parliament to Rashtrapati Bhavan. The black tarmac of Rajpath seemed washed clean as the PBG marched with military precision in the pouring rain.
Both the leaders reached the Rashtrapati Bhavan where the former took charge after signing the register.
