2 months ago I have tried to replicate the error using the same date and timezone configuration (Europe/London) in a Windows environment:
Operating System: Windows 11 Python: 3.9 Pendulum: 3.0.0 Date and time used: DateTime(2024, 8, 29, 16, 46, 14, 16970, tzinfo=Timezone('Europe/London')) Parsing result: 2024-03-02 06:00:00+00:00 without any errors.
This suggests that the issue might be specific to the Fedora 40 environment or related to differences in dependency configurations on that operating system.

2 months ago Thanks for confirming. Let me get a full ouptut of all package versions used in the venv and we can compare what is different. Here's output of pip3 freeze in the venv where I can reproduce this:
pendulum @ file:///home/sam/src/pendulum
python-dateutil==2.9.0.post0
six==1.16.0
time-machine==2.15.0
tzdata==2024.1edit: I should also note the exact python version, which is this:
Name : python3
Version : 3.12.5
Release : 1.fc40It could also be a difference between Python 3.9 and Python 3.12 based on your results

20 hours ago Note that the TZ environment variable has an impact here. On debian bookworm I see the following:
root@48ff42b03f9d:/# unset TZ
root@48ff42b03f9d:/# python3 -c 'import pendulum; print(pendulum.parse("Tue, 02 Mar 2024 06:00:00 GMT", tz="UTC", strict=False))'
2024-03-02 06:00:00+00:00
root@48ff42b03f9d:/# TZ="UTC" python3 -c 'import pendulum; print(pendulum.parse("Tue, 02 Mar 2024 06:00:00 GMT", tz="UTC", strict=False))'
2024-03-02 06:00:00+00:00
root@48ff42b03f9d:/# TZ="Europe/London" python3 -c 'import pendulum; print(pendulum.parse("Tue, 02 Mar 2024 06:00:00 GMT", tz="UTC", strict=False))'
