The design of the function datestr2num, unfortunately, has an undesired side-effect.
Today (September 30) I cannot convert monthly data, as February doesn’t have 30 days.
Conversion of:
datestr2num(‘2000-02’)
Gives an error:
ValueError: day is out of range for month
Should I file a bug report or a feature request?
Thanks,
Mark

Hello List,
When I use datestr2num(‘2010-05’) it nicely converts that to a number
representing the date.
When I convert that number back with num2date, it turns out it sets the day
to the 19th of the month. The dime is 0:00:00.
Any reason it is set to the 19th instead of the first?
Maybe because today it the 19th, or is that just a coincidence?
datestr2num calls dateutil.parser.parse, which by default uses the
current date at 00:00:00 for missing fields. The dateutil function
also can use a “default” argument to change this bahavoir but it is
not available in datestr2num.

I would classify it as a bug resulting from a bad default in dateutil.
