What exactly is Star Wars Day?
May 4 is commemorated as Star Wars Day by fans worldwide.
The date is a play on the iconic phrase "May the Force be with you", which sounds similar to "May the Fourth".
Star Wars Day has largely remained a fan initiative, with the first large-scale event organised in Toronto, Canada, in 2011.
Star Wars Day was organised in Singapore last year by Hasbro, with participants taking to Orchard Road in Star Wars costumes. Lightsaber "duels" were also held at Books Kinokuniya in Ngee Ann City and a display of collectibles was held at the Singapore Philatelic Museum.
