Perpetuum Calendar (2012)

In this video, I explain (in Swedish) how I programmed a perpetual calendar back in 2012. At that time, I was working—and continue to work—as a home caregiver for the elderly. Having previously developed a personnel reservation system, I realized that the calendar I had created could be adapted into a perpetual one to calculate any day of the week. A few years ago, I converted the original ActionScript code to JavaScript, and in this video, I showcase the result, which is as similar to the original as possible.
