Sunrise and 270° Longitude from Greenwich

• The Earth rotates 360° every 24 hours, which means it turns 15° per hour.
• If Greenwich (0° longitude) is the reference point, then 270° longitude is 18 hours ahead in rotational terms.
• However, sunrise doesn’t “arrive” at 270° longitude in any fixed sense—it depends on the observer’s location and the Earth’s rotation relative to the Sun.
• What’s true: solar noon (when the Sun is highest) occurs progressively later as you move westward from Greenwich. So 270° west of Greenwich (or 90° east) would be roughly 18 hours behind in solar time.

ha ha ha ha ha ha ha ha. bi polar dysfunction with each solstice twice a year one polar cap has a midnight sun and the other 30 days of night half a year apart. Climate change.

two days a year they have even daylight and night hours those two specific rotations.
