Hey toshibochan, if you are not used to coding or don't know how to code, this might not be the best project for you. I would rate this as an intermediate level project for coding and Raspberry Pi knowledge. This was just more of me wanting to share a project I did, and I don't have step by step installation instructions available.

Flask is a microframework for Python, and more info can be found here: http://flask.pocoo.org

Arrow is a Python library that offers a sensible, human-friendly approach to creating, manipulating, formatting and converting dates, times, and timestamps. It implements and updates the datetime type, plugging gaps in functionality, and provides an intelligent module API that supports many common creation scenarios. Simply put, it helps you work with dates and times with fewer imports and a lot less code. More can be read here: http://crsmithdev.com/arrow/
