Have a Bad Day Day is observed on November 19. 2022. This holiday was created by Ruth and Thomas Roy with the intention to encourage people to wish others to have a bad day. The background of this intention is that sales people always wish their customers a nice day when they are finished with their sales pitch. This gets repetitive for people to say and to hear. So to surprise people and throw them off guard, wish them a bad day today. It is also a good chance to be impolite without somebody noticing it. So whether you are looking for a change or want to be secretly impolite, today is the day to try it.
