Question for Community Days and Egg Hatching Bonus

You need to wait until after the event starts. Eggs incubated when the event ends keep the shortened distance.

From Bangkok where we had event already. If you have eggs in incubators b4 event they do NOT benefit from accelerated hatch rate, so wait until event starts to incubate. Important: you do NOT have to complete the hatch during the 3 hour period, you ONLY need to get the egg in the incubator and you can hatch / walk at your leisure after the event as the distance meter does NOT reset at end of event. Worst thing you can do is to have your Freebie / eternal incubator in use before the event (I did and lost precious hatch time).
