In the town of Dingle in the south-west of Ireland, locals often say that there are two seasons in the year: six months before the Wren and six months after the Wren (pronounced “wran”). It is not uncommon to hear “I’ll see you the Wren’s Day” as a greeting even more than “happy Christmas” during Christmas week itself.
As someone who grew up in the town, it is fair to say that Dingle people are healthily obsessed with it and that the Wren’s Day is the highlight of the calendar for most townspeople.
