I'm making a device that will display the weeks and days until a specific date (in this case my wifes maternity leave start). I am using a Raspberry Pi with a 4" screen. The plan is to use a python script to display full screen the weeks and days left until a specific date. The date will be hard coded into the script for now and the time will be set by a RTC module for the Pi. Any help or pointers would be appreciated as I can only find countdowns that use days/hours etc. I'll be using Python 3.x.
