Those living at Deangate Care Home, in Barnsley, joined others around the country in breaking out of old routines.
The residents decided to don their pyjamas for the day, enjoy breakfast in bed and a teddy bear picnic in the lounge while watching a classic movie.
The home’s staff all wore pyjamas and onesies and brought in dozens of toy bears for the picnic.
Julia Chambers, home manager at Deangate Care Home, said: “National Old Stuff Day is the opposite of what you might expect.
“It’s about doing something new or different, breaking out of old routines, adopting a new approach or attitude to a task or activity.
“The residents and staff decided a teddy bear picnic was a great way to celebrate the national day and everyone had a great time.”
Anyone taking part in National Old Stuff Day was encouraged to post on social media using the hashtag #NationalOldStuffDay.
