I go to a rather odd school, where we run with a 7 day timetable, 5 periods in each. One day has 6 periods. Monday - D1 Tuesday - D2 Wednesday - D3 Thursday - D4 Friday - D5 Monday - D6 Tuesday - D7 In that kind of order. I'm curious to know if there is an app I can use to store the timetable and that may also give what day in the timetable is it. Price is not an issue. Please and thank-you.
