Once in a blue moon

Image shows a moon, which is tinted violet-blue.
English has lots of moon-related idioms, including ‘to be over the moon’ (to be delighted) and ‘to ask for the moon’ (make excessive and impossible demands).
Meaning: The phrase refers to something that happens very infrequently.

Example: “I only see him once in a blue moon.”
Origins: Confusingly, a blue moon doesn’t refer to the actual colour of the moon; it refers to when we see a full moon twice in one month. This happens every two to three years. It’s thought that the word “blue” may have come from the now obsolete word “belewe”, which meant “to betray”; the “betrayer moon” was an additional spring full moon that would mean people would have to fast for an extra month during Lent. The saying in its present meaning is first recorded in 1821.

     To DAS. The expressions I like out of the ones you've  posted lately are - it takes two to tango, every cloud has a silver lining,  to kill two birds with one stone and  actions speak louder than words. They seem to be very popular.
     Moreover, actions speak louder than words is very actual at the present moment.
