What time is sunrise in Houston today?

What are first light and last light?
Civil twilight — when the sun is less than 6° below the horizon. It's bright enough for most outdoor activities before sunrise and after sunset.
Why do the times change every day?
Earth's tilted axis means the sun's path moves through the seasons — days lengthen toward the summer solstice and shorten toward the winter solstice, so sunrise and sunset shift a little every day.
