The Spirit Festival is an event for the remembrance of departed souls. You can go alone or participate with a loved one.
Attending the Spirit Festival
The Spirit Festival is on Autumn 21 each year. You can attend the event in Olive Town any time between 10AM and 7PM that day. When the event is over, you automatically return to your farm at 7PM, so be sure to take care of your livestock and crops before you begin.
Once you enter Olive Town between 10AM and 7PM on the day of the Spirit Festival, time will not pass, so you have plenty of time to talk to everyone and give people gifts for the day before you start the festival. Most people will be in the town square or playground. If you can't find someone, be sure to check the map.
How to Participate
To start the Spirit Festival, if you want to do the event alone, talk to Simon in the town square. Otherwise, you can choose to participate in the event with someone you have given a confession pendant to, or with your spouse. Talk to your desired partner to do the event with them. Saying no will not reduce your relationship with them, and you can talk to them again to do the event with them.
There are no mini-games or challenges in the Spirit Festival, so just watch the events unfold. You will automatically return to your farm at 7PM afterward. You won't be able to go back into town until the next day.
