Would it be lighter or darker in the morning? (time change)?

it's the right category, for a 14 years old, you are quite smart and you are so cute, keep asking cute questions

The best way to think of these sort of questions is by logic deduction, so, assume it gets light at 07:00 (or whatever time you wish). Lets say that this is today. Now tomorrow we advance the clocks by 1 hour so it will get light tomorrow at about 08:00 instead of 07:00 because we've put the clocks forward. So tomorrow at 07:00 it will still be dark. (Note that light/dark periods gradually change daily and continuously everywhere on Earth throughout each year. The equator remains fairly stable and at the poles its either always light or always dark depending on whether its summer or winter.)

It will be darker in the morning at 7:00 AM. The sunrise will get earlier each day

until about June 20.

But it will be lighter at 7:00 PM. The sunset will get dark later each day

until about June 20.

it depends on your location as to when the sun will rise. It does not rise until almost 8 here. Check weather.com and enter your zip code to figure out when the sun will rise in your area.
