Indian and Pakistani officials will hold confidence-building talks on nuclear issues in Islamabad next month.
The "roadmap" was agreed by the foreign secretaries in February
India's external affairs ministry said on Wednesday it had accepted the dates of 25 and 26 May proposed by Pakistan earlier this month.
Delhi said it had also agreed to drug trafficking talks on 15 and 16 June.
Pakistan and India set out a "roadmap" in February for discussing all issues dividing the nations, including the disputed region of Kashmir.
Exchange of information
An Indian official told the Associated Press that Delhi would want a briefing from Pakistan on the measures it had taken to safeguard nuclear security following the scandal involving leading scientist Abdul Qadeer Khan.
Dr Khan this year admitted passing nuclear secrets to Libya, North Korea and Iran.
The May confidence-building talks will be at expert level.
The measures discussed will include an annual exchange of information on the location of each other's nuclear installations and facilities.
The roadmap then calls for the nations' foreign secretaries to meet, probably in June, followed by a meeting of foreign ministers in August.
The roadmap was agreed at a landmark meeting in Islamabad in February - the first such dialogue in three years and the culmination of a thaw that began in April 2003.
The nuclear-armed rivals say they want to reach a peaceful settlement of all bilateral issues, including Kashmir.
They have fought two of their three wars since independence over the region.
Tens of thousands of people have died there since militants took up arms against Indian rule in 1989.
