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.

Planning around the date

For work and school planning the useful numbers are working days and weekends. Between September 11 and today there are 15 weekdays (Monday to Friday), 3 Saturdays and 3 Sundays. Take out public holidays in your region and you have a realistic count of working days that passed. If you were paid every two weeks over that stretch, that is about 1 pay cycles.
