This just started failing for me from today. It was working before. I dont know how. This isnt working on my EC2 ubuntu machine. So could be an OS issue.

I've had a quick look at this, and it seems that a change in pyparsing (a library that daterangeparser uses for its parsing) has caused daterangeparser to fail.

A quick and nasty fix is to downgrade pyparsing to v2.2.2, which works (it seems to be changes in v2.3 that cause the error). You can do this by running pip install pyparsing==2.2.2.

I'll have a look into what I need to change to get it working with the latest version

I've managed to fix this now, and have released v1.3.2 which works with the latest version of PyParsing.

Let me know if this fixes your problem.

Another example (taken straight from the docs) fails to parse the time correctly, it silently turns it into midnight:

>>> daterangeparser.parse_date_range.parse("23rd October 7:30pm")[0].isoformat()
'2025-10-23T00:00:00'
