Learn the skill

In an ideal mean-solar-time model, 360 degrees corresponds to 24 hours, or 15 degrees per hour. Eastward locations are ahead. Actual legal time zones and daylight-saving rules are not defined by this simple calculation.

Worked example

A point 30 degrees east is 2 model hours ahead because 30 / 15 = 2.

A circle divided into 24 equal angular intervals illustrates 360 degrees in 24 hours, or 15 degrees per hour. Thirty degrees east means two hours ahead in this ideal solar-time model, not a legal time-zone rule.
