He's fifty if he's a day

Please,
what does the following expression mean?

He's fifty if he's a day.

THANK YOU. KP

[SoothingDave]

It means he is at least 50 years old. He is certainly a day old. So if he is a day old, he is certainly 50.

Thanks for your explanation, SoothingDave!

It means he is at least 50 years old. He is certainly a day old. So if he is a day old, he is certainly 50.

Would it imply something like "even if you don't believe it" or "even if he doesn't look his age"?

Thank you

Greetings,

There is often that implication, Charlie.

Or that he is not acting his age, or that he pretends that he is younger.

Look at him out there, dancing with those 20-somethings, and him being 50 if he's a day!
What? She told you she was 47? What a liar. We were in 6th grade together. I tell you, that woman is 55 if she's a day!

In the opposite case, when the person is older than he is thought to be, a common reply is '...and the rest.'

A: 'Cliff Richard must be at least 60.'
B: '...and the rest. He was 70 last October.'

PS: the 'and' is not reduced - it's a full /æ/ sound.
