ONE DAY is a brand new musical based on David Nicholls’ critically acclaimed, global bestselling novel ONE DAY. It will play at the Royal Lyceum Edinburgh 27 February – 5 April 2026.
Emma and Dexter first meet on the night of their graduation, 15th July 1988 – St. Swithin’s Day. Over the next twenty years we return to them on the same day each year, and through joy and heartbreak, missed opportunities and second chances, they navigate love, ambition, and the unpredictable twists of life.
