Calendar days or exact hours?
For this page, the calendar difference compares today’s calendar date with October 16, 2017, ignoring the current time of day. It does not count the starting date as day one. If you count both calendar dates, add one. The live hours, minutes and seconds instead measure elapsed time to or from 12:00 a.m. on October 16, 2017 in your device’s time zone. Consequently, the full 24-hour-day total may differ from the calendar-day total.
