a hard day's night 

A Beatles, song, movie, and album (actually a soundtrack for the film) All three of them are absolute classics. The phrase 'a hard day's night' was actually created accidentaly by Ringo Starr, who often combined two phrases to create a new one.

a hard day's night 

The essence and summary of having lived the 'day' of ones life in 'darkness'. It has been... denotes a looking back or hindsight and the choise of the word 'hard' implies difficulty. Generally such epiphany comes sadly late.

Last minute, enlightenment is frequently found where mill stones were considdered mile stones.

Should you say it's been a hard day's night I will understand

A Hard Day’s Night 

It's been a hard day's night
And I've been working like a dog
It's been a hard day's night
I should be sleeping like a log
But when I get home to you I'll find the things that you do
Will make me feel alright

You know I work all day
To get you money to buy you things
And it's worth it just to hear you say
You're gonna give me everything
So why on earth should I moan, 'cause when I get you alone
You know I feel ok

When I'm home

Everything seems to be right
When I'm home

Feeling you holding me tight, tight, yeah

It's been a hard day's night
And I've been working like a dog
It's been a hard day's night
I should be sleeping like a log
But when I get home to you I'll find the things that you do
Will make me feel alright, oww

So why on earth should I moan, 'cause when I get you alone
You know I feel ok

When I'm home everything seems to be right
When I'm home feeling you holding me tight, tight, yeah

Oh, it's been a hard day's night
And I've been working like a dog

It’s been A Hard Day’s Night
I should be sleeping like a log
But when I get home to you I'll find the things that you do
Will make me feel alright
You know I feel alright
You know I feel alright

a hard days night 

A) the Beatles' first movie that hit the big screens in 1964. Has the same name as the album also released that year.

B) one of Ringo Starr's many idiosyncrasies

C) a cooler way of saying "I've had a tough day."

George: How was your day, then?"
Ringo: rubbish, really. It was a hard days night, you know.
