The Day of the Bright Sun is a festival to celebrate the event of Peach ending the 330-yearlong Age of Darkness by clearing the clouds and letting the sun rays shine over the land once again around 100 years prior. It occurs on the 19th day of Month 1 every year.
Prior to the festival on Day 19, Mayor Gale requests that all citizens of Portia participate in the gift-giving event by donating an item. On the day of the festival, an airship drops the gifts in the town's plazas. The townsfolk can race to get each of the gifts and claim it as their own.
The player needs to be hasty and retrieve as many gifts before the event ends. Most townsfolk will participate in the event and are able to claim the gifts. After claiming a gift, the player receives a letter of gratitude from the benefactor.
As the Day of the Bright Sun is centered around giving, giving gifts to the citizens rewards more relationship points.
