Re: [Matplotlib-users] datestr2num of year and month fails for February on September 30

[Mark B. <ma...@gm...>]

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
