First day of the week

Today is Sunday

To me Sunday is the first day of the week

But to many Monday is the first day of the week

It is hard to say who is right and who is wrong...
Since Wednesday might be the true first day in the end...

So what my logic behind Sunday being the first day...

Well... The celebrate tell me so

Nope... No just because it is on top of the rest...
But because it is red in colour
representing a holiday...

So what about it being a holiday....
So here how it goes....
Comapring 31 Dec and 1 Jan

Which one is the holiday?
Of cox it is 1 Jan...
That it because it is the first day of the year

So from there we know that the first day of the year is an holiday...
So using the same logic the first day of the week should be a holiday too

So since Sunday is in red for holiday
I took it as the first day of every week

All we need to find out now is well doesn't the first day of the month in red....
