Better late than never
It is better to do something after it was supposed to have been done than not to do it at all.
better late than never
Being tardy is better than not at all, as in We've been waiting for you for an hour—but better late than never. This phrase, first recorded about 1200, appears in several early English proverb collections, often with the added but better never late. Today it is often used in exasperation over a delay, as in the example.
