How far to the north and south?

The sun’s N-S swing, in degrees at Sunrise and Sunset depends on the latitude of the place. The Latitude of Bangalore is 12.97 deg, so the Sun’s amplitude is 24 deg.

Source :  “The angular difference between the direction of sunrise and due east, and the direction of sunset and due west is called the sun’s amplitude. The sun’s maximum amplitude is seen on each June and December solstice. The exact maximum amplitude depends on your latitude. The farther north you go in the northern hemisphere or the farther south you go in the southern hemisphere, the greater is the sun’s maximum amplitude. The following table gives the sun’s maximum amplitude for several latitudes:
