Many fans wonder how faithful Pokémon Shiny Diamond and Shining Pearl will be compared to the original version. We have already been able to know some changes, and now they raise another one that is probable as well, although in this case it has not been confirmed.

It is about a feature that was never officially announced, but found by Diamante and Perla dataminers . This feature is described like this:

This feature was that Pokémon players could find more or fewer creatures depending on the day of the year, and that was because there were several dates that would positively affect the encounter rate of wild Pokémon and other dates that would decrease it. On happy days, national holidays for different countries, and global holidays, the encounter rate would increase by 10 percent, resulting in the appearance of more wild Pokémon.
