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 smaller. 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.

About Fall (September Equinox)

The September equinox, the astronomical start of Northern Hemisphere autumn, computed each year from the sun's position. Fall (September Equinox) marks an astronomical turning point in the year, which is why it is used to mark the start of a season in almanacs even though meteorologists count seasons by whole months.

Fall (September Equinox) is the moment the sun reaches a particular longitude in its apparent path, calculated astronomically for each year. The date can shift by a day between years because the tropical year is not a whole number of days.
