BUR #20182 has been rejected.
create implication happy_anniversary -> anniversary
create implication happy_birthday -> birthday
create implication merry_christmas -> christmas
create implication happy_easter -> easter
create implication happy_halloween -> halloween
create implication happy_valentine -> valentine
create implication happy_white_day -> white_day
It's time for this vote. I can't remember the amount of times I tried to look for birthday posts only to realize it's practically useless because 90% of them are under happy birthday.
Taking happy new year out for the moment cause currently chinese new year doesn't imply new year. And someone confirm me if happy holidays can be used for holidays other than christmas.
