Switzerland has declared May 26 as Science Day in honour of visiting President A P J Abdul Kalam.
The Swiss government, considering his vast expertise in science and technology, announced this following his arrival in Geneva on Wednesday.
Kalam is on a four-day state visit.
Switzerland considers the President as the father of India's missile programme.
Kalam is the first Indian head of state to visit Switzerland after a gap of more than 30 years. Former President V V Giri was the last high profile person to visit the country.
