Throughout Pokémon Brilliant Diamond and Shining Pearl, there are different things that can be done once a day or on specific days of the (real world) week. It can be important to take advantage of them if you are looking to maximize your gameplay.
Things that can be done daily
These activities will reset based on the real-world day and time as set on your Nintendo Switch and can be done daily in Pokémon Brilliant Diamond and Shining Pearl.
Floaroma Flower Shop daily berry
A woman in the Floaroma Flower Shop will give you a berry each day.
Jubilife TV battle corner
On the first floor of the Jubilife TV building in Jubilife City, a trainer will show up each day in the top left-hand corner of the first floor. They will battle you once per day.
Pastoria City daily berry
A girl in the home west of the Poké Mart will give you a berry each day.
Pokémon Lottery Corner
The Jubilife TV building in Jubilife City houses the Pokémon Lottery Corner. The lottery will draw a random number and check it against the Trainer IDs of your Pokémon’s original trainer. For better lottery odds, trade with other trainers.
In the Jubilife TV building in Jubilife City, there is a TV Producer on the third floor (standing next to a woman) who will ask you about your favorite TV programs. You can get Ball Capsule Stickers from him. This is all the same NPC who can unlock Mystery Gift early.
Possible rewards: Flora Sticker E
Veilstone City massage
In a home of the Veilstone Gym, a woman will offer to give a massage to one of your Pokémon once a day. This will boost its Happiness and is helpful for evolutions that require a Pokémon to be friendly with you.
She may also find Ball Capsule Stickers, such as: Sinister Sticker C, Leaf Sticker B/C, and Spark Sticker B (gifted sticker may depend on type of Pokémon that got the massage)
On Fridays, a Drifloon will appear in front of the Valley Windworks building. The screenshot shows the location of its appearance and will be updated when we have a chance to encounter it.
