 The ending of Netflix’s latest hit show, One Day, has left fans sobbing, but how does the story end, and what is the significance of St Swithin’s Day? 

One Day is Netflix’s latest hit romantic drama which tells the story of university graduates Emma Morley (Ambika Mod) and Dexter Mayhew (Leo Woodall), who meet for the first time on 15th July, the night of their graduation. They spend the whole night talking, and by the time the morning comes, they decide to remain friends.

We see Emma and Dexter experience all the highs and lows of their personal and professional lives while also seeing how time affects their friendship and romantic bond.
