The Epiphany: It would be really fun to have this Christian holiday added. For those who don't know, it's the day the three wise men visited baby Jesus to give him gold, myrrh and incense. It's celebrated in several European and Latin American countries, as well as other Catholic ones with different types of baked goods, depending on the country. It's also common for the kids to receive small gifts on this day, so it'd be fun to receive some as well. It's celebrated on January 6th.
Spring Festival: We really don't have yet a spring festival, so it'd be fun to celebrate the arrival of spring, with lots of flowers blooming, butterflies and bugs flying, and in the main plaza some games or activities related to flowers or bugs. Everyone should be out, enjoying the spring weather. It should be on March 1st. Even picnics could take place.
Cherry Blossom Festival: We do have cherry blossom trees, but we lack a festival. There should be a festival on main plaza with cherry blossom rated activities or clothes. Maybe catching the cherry blossoms? It should take place on the first day of Cherry Blossom.
Beach Day: This could be a really fun day with the villagers hanging out in the beach, with music, playing games or beach sports. They could be swimming or just laying in the sand. It could be fun to get some cool summer vibes in this game. It could be any Saturday of July, but I'd say the second.
The Olympic Games: As the Olympics take place in august, it would be fun to have something similar to that game of Animal Crossing which had Sports Day, with aerobics, races, and other minigames.
Fall Festival: There should be a fun festival at the main plaza celebrating the arrival of fall. There should be some activities related to trees, or collecting fruits, bugs, or
Acorn Day: Just like in that game, the same idea.
Beginning of Advent: As the holidays are approaching, it's time for Advent, a day in which you should prepare yourself for Christmas. You should get a gift as well.
You should also be able to create your own events, or at least one celebrating the day of the town. You should choose the day in which it happens.
I would also like to point out that events should be more interactive in future games. Villagers should be more involved in them, and you should get more things than just furniture, like money.
These are my ideas. What do you think about them?
