pytz and astimezone() cannot be applied to a naive datetime

Question

I have a date and I need to make it time zone aware.

local_tz = timezone(\'Asia/Tokyo\')
start_date = \'2012-09-27\'
start_date = datetime.strptime(start_dat         


        

Answer 1

You could use local_tz.localize(naive_dt, is_dst=None) to convert a naive datetime object to timezone-aware one.

from datetime import datetime
import pytz

local_tz = pytz.timezone('Asia/Tokyo')

start_date = local_tz.localize(datetime(2012, 9, 27), is_dst=None)
now_utc = datetime.utcnow().replace(tzinfo=pytz.utc)

print start_date > now_utc

is_dst=None forces .localize() to raise an exception if given local time is ambiguous.
