Introduction to Time Based Sun Direction

Time Based Sun Direction problems ask for the position of the sun or the direction of shadows at a given time of day. The sun rises in the East, sets in the West, and is in the South at noon (in the Northern Hemisphere). These problems test your knowledge of daily sun movement patterns.

Prerequisites

Knowledge of sunrise (East) and sunset (West) Understanding of noon sun position (South in Northern Hemisphere) Basic time of day concepts (morning, afternoon, evening) Shadow direction opposite to sun direction
Why This Matters: Time Based Sun Direction problems appear in 1-2 questions in SSC CGL and Banking PO exams. They test practical knowledge of sun movement.

How to Solve Time Based Sun Direction Problems

1

Step 1: Identify the given time of day (morning, noon, afternoon, evening)

2

Step 2: Recall sun position rules: Sunrise (6 AM) = East, Noon (12 PM) = South, Sunset (6 PM) = West

3

Step 3: For times between, interpolate: morning sun is in East/Southeast, afternoon sun is in West/Southwest

4

Step 4: For shadow direction: shadow is always opposite to the sun's direction

5

Step 5: If sun is in East, shadow points West

6

Step 6: If sun is in South, shadow points North

7

Step 7: If sun is in West, shadow points East

8

Step 8: Apply the appropriate rule based on the question

Pro Strategy: Remember: Sun East → Shadow West; Sun South → Shadow North; Sun West → Shadow East. For morning hours (6 AM to 12 PM), the sun moves from East to South; for afternoon hours (12 PM to 6 PM), the sun moves from South to West.

Example Problem

Example: At 6:00 AM, in which direction does a person's shadow fall? Solution: Step 1: Time = 6:00 AM (sunrise) Step 2: Sun rises in the East Step 3: Shadow direction is opposite to the sun Step 4: Opposite of East is West Answer: West

Pro Tips & Tricks

  • Sunrise (≈6 AM): Sun in East, shadow in West
  • Morning (8-10 AM): Sun in East-Southeast, shadow in West-Northwest
  • Noon (12 PM): Sun in South, shadow in North
  • Afternoon (2-4 PM): Sun in West-Southwest, shadow in East-Northeast
  • Sunset (≈6 PM): Sun in West, shadow in East
  • In the Northern Hemisphere, the sun never reaches North

Shortcut Methods to Solve Faster

6 AM: Sun East → Shadow West
12 PM: Sun South → Shadow North
6 PM: Sun West → Shadow East
Morning shadows point West/Northwest
Afternoon shadows point East/Northeast

Common Mistakes to Avoid

Confusing sun position with shadow direction (they are opposite)
Forgetting that noon sun is South (Northern Hemisphere assumption)
Assuming sun is directly overhead at noon (it's at South, not overhead except at equator)
Applying Southern Hemisphere rules to Northern Hemisphere problems
