December 2019 Community Day

The December 2019 Community Day was the 24th Community Day in Pokémon GO and the last one scheduled in 2019. It was a two-day event featuring all Pokémon from 2018 and 2019 Community Days.

Features
The two day event occurred from 9 a.m. on December 14 to 9 p.m. on December 15 in your local time zone. Exclusive moves for the Pokémon were obtainable in the whole time slot.

However, the Pokémon appearances were only featured from 9 a.m. to 9 p.m. on each day and some minor differences between two days. In simple words:
 * The 2019 Community Day Pokémon appeared in the wild on both days.
 * The 2018 Community Day Pokémon appeared in tier 1 Raid Battles on both days.
 * The first half of both years and the second half of both years Community Day Pokémon appeared in the Eggs on Saturday and Sunday respectively. (Pichu in Pikachu case)
 * Extra bonuses occurred from 11 a.m. to 2 p.m. on each day, including double catch Stardust and XP, half Egg distance and 3-hour lures.
 * The first half of 2019 and the second half of 2019 Community Day Pokémon appeared in wild more frequently on Saturday and Sunday respectively.

Trivia

 * Shadow Pokémon remained Frustration when evolved while Purified Pokémon could learn the exclusive moves, replacing Return.
 * Only Shadow Tyranitar could learn exclusive move because Smack Down is a Fast Attack.
 * All Eevee caught or hatched from Eggs obtained in the Community Day could learn Last Resort.
 * Evolution of Eevee, including Leafeon and Glaceon, could learn Last Resort whatever the Eevee had Last Resort.
 * Pikachu evolved from Pichu could learn Surf, including the costume versions.
