"Two-days community events mean that on the first day you can catch full time, rate in the evening and evolve the following day."

#PokemonGO: Unless there is an exclusive evolution each day (in that case we will know at least after the first time zone), on the first day we can avoid thinking about evolution at all and maximize the catches, so high ivs and shinies. The when we get more than 20 hours to rate in peace and to take note also of what shinies you can skip rating the next day (for example, if I have 7 shiny eevee already from first to third good ivs tier, it means that i don't have to rate those in the fourth tier). via /r/TheSilphRoad https://ift.tt/2uuTyX6
