Shamrock Day

Shamrock Day is a holiday in that takes place on March 17th, which is the same day as St. Patrick's Day. During the day, Isabelle can be found next to the Town Tree in the Event Plaza (or near the Town Hall if the event coincides with the Fishing Tourney like in 2018). If the player talks to her, she will inform about the holiday and give out a Shamrock Hat.
