St. Patrick's Day
On St. Patrick's Day (March 17), when you pet your puppy or kitten, clover-shapes will pop up

Change the Date
At the end of the day, you can change the 3DS's system date to a day ahead and you can do things like competitions, tricks, etc. then save and switch it back to the current date. The game saves all data from future dates.
