When a new year dawns it’s time for Run it up the Flagpole and See if Anyone Salutes Day on January 02, 2022. This fun holiday goes back to a vintage English idiom. It is a good bet for someone who has made up an idea and does not know yet if it is a good one. Running it up the flagpole would be a good way to let the public know about it. A modern variation of this catchphrase would be: “Send up a trial balloon”.
If anyone salutes, meaning appeals on your idea, then maybe it is a good one indeed. The unknown inventor of Run it up the Flagpole and See if Anyone Salutes Day motivates ambitious people to test their fancies so that they can get started with it, no that the new year has just begun. Anyway this expression is a bit outdated and therefore rather funny than serious.
