About a month give or take. I have quite a heavy work-load right now so the time wasn't entirely dedicated to this single project. A rough estimate in hours would be 20-30 or so I think..
Wappler and Dreamweaver (95%). I did open up Pinegrow occasionally. But predominately Wappler based as I need to catch up with my lack of education of the product as it stands right now.
The calendar is based on Fullcalendar (https://fullcalendar.io/). Free to use and implement. I deployed full CRUD capabilities via pop-ups (with nice date range selectors) as well as cookie based on click options and triggers for moving data around the db based on changes etc (also translates when the language cookie is updated).
I did upload an example right here but it didn't get that much attention 
Feel free to download it and rip it apart for a good idea of whats going on. JSON based dictionary powers the language with on click events to set the cookie.
Hope that all helps mate! Thank you for your kind feedback.
