Background

We'd like to do more calendar integrations with SnapHabit. "ICS" is a calendar format we'll need to become more familiar with.

Deliverable

• Create a program which
  • takes as arbitrary input: ICS file and start date (eg. date for the first event)
  • generates output: ICS file that is shifted such that the first calendar event is on the new input date. All calendar events should be shifted appropriately, see example below.
• Include README file with instructions for how to run the program

Bonus

The initial use case is a website that allows users to download a hosted calendar that starts on the date a user submits. As a bonus project, setup a webpage that either

• allows a user to upload an ICS file and return a download link with the altered ICS file.
• hosts an ICS calendar and allows users to change the start date and returns a modified calendar

Details

• Use Python or Javascript (node.js) for the implementation
• Do on your own time (eg. unsupervised)

Sample Input Files

JusticeJune.ics

• Currently the first event on the calendar in on June 4

• If the inputed date is 6/15, content from 6/4 be shifted to 6/15. Content from 6/5 should now be on 6/16, etc.
