Call me crazy but did it? I could have sworn a few years ago around this time of year (June) I would be up at 5:30AM to get ready for school and it would still be pitch black outside. But flash foward a few years later and now at 5:00AM the birds are chirping. When will it be again that the sun starts rising at 6AM or 7AM? I miss those days. I know the days in the summer now are longer than the nights. But I don't remember daytime starting at 5AM! So is there a reason why this is happening? Are we getting farther away from the moon or something? It's just making me mad because I go to bed around 4:30AM and I hate trying to fall asleep as the sun rises. I HATE IT!

Have you always been in an area that used daylight savings time?
We are approaching the summer solstice. The sun is rising earlier this time of year than at any other. (Except in the southern hemisphere.)

The Earth orbits the Sun on a yearly basis. However due to relative change of mass of the Sun -Earth system ,the earth's orbit expands and the spin of the earth slows down and the precession of the poles changes accordingly.
Therefore the time of Sun rise at a particular day should also change from year to year.However this change is only by very minute increments,that we can hardly notice it;but its there.
NOte as the Earth orbits the Sun its radius continuoulsy changes and so is the instantaneouse time.The reason is that the orbit is elliptical.
The Sun does not abruptly appear instaneously. It slowly appear as a twilight in the the morning.So the time of full rise is when the sun is just above the event horizon.
The sunrise time is therefore a function of the Earth's position relative to the sun, that is why in the winter the Sun rises later than in the Summer.

No.
The sun rises early starting March 23 in a small amount of time
the sun earliest rises will be on June 23

the reason to this is that the tilting of the earth 23 1/4 degrees
from its plane of revolution

the first two line statements is good only to areas in the northern hemisphere

in the southern hemisphere the happening is reversed
During March 23 to June 23 the sun rises late

Your memory fails you. The sunrise is on the same schedule as the last uncountable years.

Did you move recently? Sunrise/sunset times are affected by where you live.
