I checked an app and saw that today, the sunrise and moonrise time are almost same. The sunset and moonset time are also same. Why does this happen?
I have always known that moon rises at night and sets at dawn.

That's called New Moon and happens roughly once a month.
It's when (viewed from earth) the moon, circling the earth, is in the same direction as the sun. So, by rotation of the earth, both become visible (sunrise/moonrise) and invisible (sunset/moonset) at roughly the same time.
Moon is then hardly visible for two reasons:
Two weeks later, we have Full Moon, the moon is opposite to the sun, it rises when the sun goes down and goes down when the sun rises, meaning that it's visible at night. And the side facing us gets full sunlight, so the moon becomes a very bright object on night sky.
