Till when sleep

[tufguy]

Can I say "Till when or what time would you remain up". If I want to ask a person that when would he sleep?

 

[Matthew Wai]

'Up to what time will you stay up?'

Not a teacher.

 

[MikeNewYork]

Too many uses of "up" there.

When are you going to bed/sleep?
How late will you be up?

 

[tufguy]

If we have to say it with "Time" then?

 

[Rover_KE]

'What time will you be going to bed?'

 

[tufguy]

Can "Time" be used with "Up"?

 

[emsr2d2]

What time will you stay up till?

 

[Tarheel]

Why would you have to use "time" in the sentence?

 

[Matthew Wai]

Perhaps the OP wants an exact time as the answer.
Not a teacher.

Too many uses of "up" there.

Is 'two' too many?

 

[MikeNewYork]

In that sentence, yes.

 

[tedmc]

Until what time will you stay up?
Not that the two 'up's' are wrong.
