Jatin–Lalit are a Bollywood film composer duo consisting of Jatin Pandit and his younger brother Lalit. They have written the scores for films such as "Khiladi", "Jo Jeeta Wohi Sikandar", "", "Dilwale Dulhania Le Jayenge", "Yes Boss", "Jab Pyaar Kisise Hota Hai", "Kuch Kuch Hota Hai", "Mohabbatein", "Kabhi Khushi Kabhi Gham" and "Fanaa" .
Jatin Pandit is at least a year older than Lalit.
It is unlikely but still possible that Jatin is just 9 months or so older than Lalit, rather than at least a year. The algorithm doesn't know the length of human pregnancy, maybe!
