The term “dawn” is synonymous with the start of morning twilight. “Sunrise” occurs the moment the disc of the sun peeks above the eastern horizon due to the Earth’s rotation. “Sunset” is the opposite. It occurs the moment the disc of sun completely disappears below the western horizon.
Technically speaking, the golden hour happens when the sun is below 6* in the sky. In the morning the “hour” will begin before the sun breaks the horizon (when it’s about 4* below the horizon) and then ends when it goes above 6*. Just reverse that for the evening golden hour
