Celebrated on the first Friday of August every year, BITSians' Day is BITS Pilani's multi-location global alumni reunion. Since its inception in 2013, the participation has constantly increased, with BITSians' Day 2016 being organised across 180 locations in 25 countries. The event also witnesses all the BITSians across the globe taking part in "wear your BITS T-shirt to work" day.
