How is the Timezone Meeting Planner calculated?

Pick your city and the other person's, then a time that suits you. Mondo converts it and works out the window where you are both inside a normal working day. The maths is short enough to check by hand: Overlap = the hours where both clocks sit between 08:00 and 18:00 local time on the chosen date.
