Asked whether Singh will be able to squeeze in a trip to Pakistan before the upcoming Lok Sabha polls, Indian officials said: "We haven't got anything planned".
Singh was born in Gah village on September 26, 1932.
While accepting in principle an invitation by Pakistan Prime Minister Nawaz Sharif to visit that country, Singh had made it clear that he would undertake the trip only if there is a possibility of a "substantive" outcome.
New Delhi is also agitated that Mumbai attacks mastermind Hafiz Saeed is being permitted to roam around free in Pakistan and also make provocative anti-India speeches.
