Weather Dates
Some maps have varying weather that depends on the current date. For example, some days have heavier rain than others; this looks different in the overworld, but still provides the standard rain effect in battle. Year can be anything for these, all that matters is month and day.
This mechanic has time travel protections, meaning that if you try to modify your system date to go straight to one of these dates, the weather that's supposed to be present will not be. For Sinnoh, this means the game uses the weather corresponding to January 1st. In Johto, this means you are guaranteed hail at Mt. Silver's Peak. Instead, you must change the date to one day before one of these dates, save in game, then wait approximately 24 hours.
Johto
In Pokémon HeartGold and SoulSilver, the only locations that seem to have varying weather are Lake of Rage and Mt. Silver's peak, where you battle Red. The Lake of Rage is rainy, but has no weather on Wednesdays. Mt. Silver is normally hailing, but on the following dates you experience Diamond Dust:
| January 1st | January 31st | February 1st | February 29th |
| March 15th | October 10th | December 3rd | December 31st |
Sinnoh
In Pokémon Diamond, Pearl, Platinum, Brilliant Diamond, and Shining Pearl, Routes 212, 213, 216, Acuity Lakefront, and Snowpoint City vary in weather depending on the date.
I haven't confirmed the dates for Diamond and Pearl yet. Anubis dug up the dates that work for BDSP, you can view them here. Here are the weather patterns for Platinum:
