Hi, this is Jack from Project Working Hours Plugin, I'm currently collecting popular days as the plugin would provide an ability for user to choose a preset when creating a excluded date.

We've prepared some days, but it'll be great if we keep an open mind and could hear some of yours'

If you are interested in this plugin, feel free to fill any days which you think that may help.

The result will be shared in gitter channel
https://gitter.im/jenkinsci/working-hours-plugin before August 20th

And if you have any suggestion or idea to share, we'll be glad to listen to you in the above gitter channel.

Thanks for reading!
