This page is not a snapshot. The figures are recalculated every time it loads, using the Asia/Karachi time zone, so tomorrow the count will be one day larger. If you bookmark the page you will always see the current gap rather than the number that was true on the day you saved it, and nobody has to edit anything for that to stay correct.
