“A pub is for life, not just for Christmas” is a saying that has been printed on many T-shirts. The saying became popular in United Kingdom pubs from at least 2003, promoting year-round pub use.
 
     
15-30 December 2003, New Statesman, “Northside” by Andrew Martin, pg. 118:
Early Advent, and I’m rattling about London’s West End with an hour to kill. It’s 8pm, freezing cold, and the pubs are bursting with hearty Cockneys. One of my favourites, the Lamb & Flag in Rose Street, carries a notice reading: “A pub is for life, not just for Christmas.”

A pub is for life, not just for Christmas
POSTED BY PETE GREEN ⋅ 10 JANUARY 2012
With the tree down, but pine needles still lacerating my bare feet, it’s the perfect time for a catch-up on festive pubgoing. Christmas and new year are fascinating times for lovers of the pub. We see our boozers heaving with happy, sociable folk, enjoying an easy journey from stranger to friend, radiant in the simple pleasure of company. Mind you, the best pubs are like that all year round, of course.
