Meaning of ‘Let Bygones Be Bygones’
This is an English phrase that is said when someone wants past problems to be forgotten about and they desire to go back to being on friendly terms.

The Origin of ‘Let Bygones Be Bygones’
Before talking about the origin of the phrase ‘let bygones be bygones,’ let us first touch briefly on the meaning of this word. A ‘bygone’ is something that is in the past. So for example, if someone was having a conversation and old memories were bought up that the person didn’t want to talk about, they might say: “I don’t want to talk about old bygones.”
According to Dictionary.com, the origin of the word “bygone” is somewhere between 1375-1425. Unfortunately, I could not find any examples of the word being used during those years. The earliest known appearance of it that I have seen is from the Shakespeare play The Winter’s Tale, 1611:
“The by-gone day proclaim’d: say this to him.”
What about the full phrase ‘let bygones be bygones’? Its first known use is in a work by Samuel Rutherford, 1636:
“Pray that byegones betwixt me and my Lord may be byegones.”
Since this expression dates back to 1636, that would make it, at minimum, 384 years old. A lot of phrases come and go in that amount of time, but this one has stuck around and is commonly used today.
