Sahil is of Indian origin, derived from the Sanskrit word 'Sahila', which means 'calm' or 'tranquil'. It's a unisex name, though it's more commonly used for boys. The name gained popularity in India and later spread to other countries through immigration. Sahil is also associated with the concept of 'Sahil ka Ghar', meaning 'home by the shore', which reflects its coastal origins.
The name Sahil experienced a significant rise in popularity from the late 1980s to the early 2000s, with a notable peak in 1998 (133 births) and another high point in 2001 (144 births). However, it seems to have declined in recent years, with fewer than 75 births recorded annually since 2014. As of 2023, Sahil has been given to a total of 3040 newborns over the past four decades.
