The direction in which the sun rises

At the vernal equinox and autumnal equinox, it rises due east. From the vernal equinox to the autumnal equinox, it rises from the northeast. From the autumnal equinox to the following vernal equinox, it is angry from the southeast.

The specific angle can be worked out, but it is too troublesome and needs drawing to solve it. It also needs the date and the location of the direct point of the sun.
