I am a big believer in the helpfulness of digital calendars. Both at home and school, I have detailed schedules marking out all of my temporal obligations for as far out into the future as I can.

My school, like I am sure many others, has a rotation schedule that matches no calendar software on the planet. For many years I was forced to copy and paste each of the four calendar permutations throughout the school year to get my class rotation into my school calendar.
