I am trying to work with django and converting timezones between UTC and my timezone ("America/Winnipeg"), but I keep running into issues and I think there might be a bug. Here is my code: #UTC to "America/Winnipeg" utc1 = datetime.datetime(2025,4,8,12,00) utc1 = utc1.replace(tzinfo = pytz.utc) utc2wpg = utc1.astimezone(pytz.timezone("America/Winnipeg")) wpgb2utc = utc2wpg.astimezone(pytz.utc) print(f"UTC Time: {utc1}") print(f"UTC to Winnipeg Time: {utc2wpg}") print(f"Winnipeg back to UTC Time: {wpgb2utc}") #America/Winnipeg to UTC wpg1 = datetime.datetime(2025,4,8,7,0) wpg1 = wpg1.replace(tzinfo = pytz.timezone("America/Winnipeg")) wpg2utc = wpg1.astimezone(pytz.utc) utcb2wpg = wpg2utc.astimezone(pytz.timezone("America/Winnipeg")) print(f"Winnipeg Time: {wpg1}") print(f"Winnipeg to UTC Time: {wpg2utc}") print(f"UTC back to Winnipeg Time: {utcb2wpg}") When you run the UTC to "America/Winnipeg" block, you get the output: UTC Time: 2025-04-08 12:00:00+00:00 UTC to Winnipeg Time: 2025-04-08 07:00:00-05:00 Winnipeg back to UTC Time: 2025-04-08 12:00:00+00:00 But when you run the exact same timezone converting back from Winnipeg to UTC, you get this output: Winnipeg Time: 2025-04-08 07:00:00-06:29 Winnipeg to UTC Time: 2025-04-08 13:29:00+00:00 UTC back to Winnipeg Time: 2025-04-08 08:29:00-05:00 There is clearly a discrepancy in the timezone conversions. Is there an issue with my code or is there an issue with the pytz library's conversion. Are you having the same output? I am using Python 3.13 Continue reading...
