From the NHSE github it has all the BCAT flags for this update.
May Day, Bride Day, International Museum Day
All three are BCAT events and require BCAT flags from flag 001 to 004 which is different from easter's 000. So unfortunately these events won't run AT ALL on Emulators (Ryujinx, Yuzu) unless more save file research is done and all hacked switches must inject the BCAT flag as before with 3 new BCAT flags.
Ok to make it clear for everyone:
April 23 - May 4: Nature Day (NO BCAT FLAG NEEDED, just install the 1.2.0 update)
Hemisphere: North and South
What is it? One of the originally confirmed Animal Crossing: New Horizons events is Earth Day, or as it's known now Nature Day. In real life, this event takes place on April 22, but in New Horizons this event runs from April 23 to May 4.
Things to watch out for: During this event, you'll be able to tick off special Nature Day themed Noook Miles challenges that are focused on nature-inpsired goals, like planting trees and watering flowers.
No doubt it will also tie into the arrival of Lief's Garden Shop too. The nature-loving sloth will start visiting your island regularly to sell an assortment of foliage, and flower seeds too.
May 1 - 7: May Day Tour (NEEDS BCAT FLAG)
Hemisphere: North and South
What is it? The first week of May is now known as the May Day Tour in Animal Crossing: New Horizons, which will earn you a special May Day Ticket to use at the airport.
Things to watch out for: During this period, you'll be able to use a one-time use May Day Ticket at the airport to fly over to a special May Day island. There's a special visitor there, items to collect, and a maze to navigate by the looks of things too.
May 18 - 31: International Museum Day (NEEDS BCAT FLAG)
Hemisphere: North and South
What is it? It might sound like a 24-hour event, but International Museum Day is a celebration of Blathers' museum that runs across almost two full weeks.
Things to watch out for: You'll receive a special Stamp Card that you can complete by viewing fish, insects and fossils at the museum. You'll get an in-game reward for completing them all.
Handily, the museum will have had an upgrade by then, with an art gallery added that you can fill with painting and sculptures. And yes, Redd is back too.
June 1 - 30: Wedding Season (NEEDS BCAT FLAG)
Hemisphere: North and South
What is it? A whole month to celebrate weddings and nuptials in New Horizons.
Things to watch out for: Head over to Harvey's island in June to meet Reese and Cyrus, who are celebrating their wedding anniversary. Help them take photos to mark the occasion, and you'll get wedding-themed items as a reward.
