import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29)
# Step 1: Create a new timezone for US/Pacific, which is 8 hours behind UTC (UTC-08:00).
pacific = datetime.timezone(datetime.timedelta(hours=-8))
# Step 2: make a new variable named hill_valley that is naive with its tzinfo attribute 
# replaced with the US/Pacific timezone you made.
hill_valley = datetime.datetime(2015, 10, 21, 4, 29, tzinfo=pacific)

# EDIT: hill_valley should be derived from naive and not recreated from scratch:

hill_valley = naive.replace(tzinfo=pacific)

Nevermind I passed with this:

import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29)
timezone = datetime.timedelta(hours=-8)
hill_valley = datetime.datetime(2015, 10, 21, 4, 29, tzinfo=datetime.timezone(datetime.timedelta(hours=-8)))

On the next challenge, I couldn't pass with this: import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29) timezone = datetime.timedelta(hours=-8) hill_valley = datetime.datetime(2015, 10, 21, 4, 29, tzinfo=datetime.timezone(datetime.timedelta(hours=-8))) timezone = datetime.timedelta(hours=1) paris = datetime.timezone(datetime.timedelta(hours=1)) hill_valley.astimezone(datetime)
