sun time changing


sun change: we start simply: at different locations on our planet we expect sun-visibility to differ. for example in the state fo georgia U.S. savannah on the coast sees the sun at a different time, than atlanta georgia, that is simple but what about the CHANGE? we know that the months in the end of spring season and beginning of summer have many sun hours. yet already in the end of spring season there is a change. until june the time between sunrise-events [horizon setting uncovering sun in morning] is shortening, adding sun time. we also kknow that during summeer season the length of sun-time shortens until the lengths of nyt and day are equal. so when is the change? 
that depends on how far north you are.
starting from famous new york city:
nyc? jun 13 change: stopd add sun-time. until then each morning had a few seconds of sun added but then it stopped adding. later less sun-time in morning, yet still adding sun time before evening.
further south from nyc, in the state of georgia, i chose kuz many people like the religious idea of israel and that state is same north as israel  is.
georgia is much larger in area and in north-length than israel.
back to the topic:  when is the CHANGE?
in the citys Atlanta and Columbus GA, both same pattern [at different times of sunrise kuz different locations as above], june 10  measuring minutes and seconds, added sun visible as before so not change yet. atlanta is 33.7n, in contrast to a northern city in israel: haifa 32.8n, between atl. to savana at 32.1n
on date 11: atl changed stopd add sun, svn also changed same date, less sun, like clm ga 32.5n, measurably less sun but in atlanta not until 12 measurably less sun seen.
further south differs:
miami changed on 8th june stopd add. from then less sun each morning until short days of autumn.
