From Tor anders Berge:
Shiftcalendar generator for people working shift both onshore and offshore.Default setting are for offshore personnel in Norway, but it can be used for all kinds of shifts. Select the date when your next working period starts, put in the name you want on the calendar, select which year you want to generate, and press generate in the bottom. If you work another shift / rotation, simply "add shift" and put in how many days you are working followed by days off, and generate calendar.When calendar is generated, use "share" function in top right corner to save to camera roll, e-mail, or share on Facebook with friends and family.
