Hello, I am getting stuck on this question. Help is appreciated.

naive is a datetime with no timezone.

Create a new timezone for US/Pacific, which is 8 hours behind UTC (UTC-08:00).

Then make a new variable named hill_valley that is naive with its tzinfo attribute replaced with the US/Pacific timezone you made.

import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29)

pacific= datetime.timezone(datetime.timedelta(hours=-8))
hill_valley = datetime.datetime(naive, tzinfo=pacific)

Your assignment of the "pacific" timezone looks good! But you'll need a different syntax to make use of it.

Hint: the "astimezone" method can be used to convert a datetime to a different timezone.

Trying this but still getting an error. 

import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29)

pacific= datetime.timezone(datetime.timedelta(hours=-8))
hill_valley = naive.astimezone(tzinfo=pacific)

According to the Python documentation page, the name of the argument to "astimezone" is not "tzinfo" but just "tz".

But since it only takes one argument, you don't really need to name it.

Very good, that worked!

naive = datetime.datetime(2015, 10, 21, 4, 29)

pacific= datetime.timezone(datetime.timedelta(hours=-8))
hill_valley = naive.astimezone(tz=pacific)
