Lying brothers

Question

You know the drill. Generally they tell the truth, but sometimes they lie. For Bill the lying days are Monday, Tuesday and Wednesday. For his brother John, the lies are told on Tuesday, Thursday and Saturday. 

Recently the three of us had a chat:

Me: Hi, what’s your name?

Older brother: I’m Bill. 

Me: What day is it?

Older brother: Yesterday was Sunday. 

Younger brother: And tomorrow is Friday. 

Me: Wait. That doesn’t add up. Are you sure you’re telling me the truth?

Younger brother: I always tell the truth on Wednesdays  

What day was it, and what is the name of each boy?

is Older = Bill? “Yesterday was Sunday” cannot be true, because Bill lies on Monday, and any other day it would be a lie. And that implies that he lied when he said he’s Bill.

So Older = John, and he lied when he identified as Bill, so today is either Tuesday, Thursday, or Saturday. Younger (Bill) says tomorrow is Friday. Then Younger (Bill) says he always tells the truth on Wednesday, which is a lie. 

As they both are lying, today is Tuesday, because it’s the only day they both lie.
