Get the Calendar in Pokémon Diamond and Pearl by showing a man in Sunyshore City a Pokémon with a Serious nature.
The Calendar shows the days of the month, the current date, and allows you to draw memos on them.
Location: In Sunyshore City, there is a house you have to Rock Climb (a technique to scale certain rocky surfaces) to access. Inside, a man will ask you to show him Pokémon with different natures (a characteristic that affects a Pokémon's stats). To receive the Calendar, you must show him a Pokémon with a Serious nature.
Tips
- You may need to catch several Pokémon to find one with a Serious nature.
- Check the nature of your Pokémon in their summary screen.
