Other similar projects

When I start to code, I did check for some similar projects.

I knew about python-dateutil, a great project I use for years... I'd like something more straightforward or simpler.

After to publish the python-networkdays on PyPi I found some others 8(

• workdays : A 5 years old project, looks the same as networkdays
• timeboard : A more complex but powerful project
• python-dateutil is great, powerful but even more complex.
• python-bizdays : Quick simple and direct ...

I will try to keep this list updated...
