How to find yourself with a star and a clock

Two numbers place you anywhere on Earth: latitude (how far north) and longitude (how far east or west). For a thousand years, sailors read both straight off the sky — no satellites, just a measured angle and the time.

  • ⭐ Latitude from the North Star. Polaris sits almost exactly over the North Pole, so the angle it makes above your horizon is your latitude. 40° up = 40° North.
  • 🕰️ Longitude from a clock. Earth turns 360° in 24 hours = 15° an hour. Carry a clock set to home, compare it to your local noon, and the time gap tells you how far around the world you are.
  • 📏 Distance from degrees. One degree of latitude is about 60 nautical miles — the mile was defined that way — so an angle in the sky becomes a distance on the sea.

Everything runs on your device — no internet, no accounts.

Meet the crew — the sky’s four instruments

  • Polaris holds still over the pole so its height above the horizon reads out your latitude, degree for degree.
  • Chrono the ship’s clock keeps home time, turning “when is MY noon?” into “how far west have I come?”
  • Meridian (mentor) draws the invisible north-south lines and reminds the crew that 15° of longitude is exactly one hour of turning.
  • Wayfinder steers by the stars that always rise in the same place — the Pacific navigator’s star compass.
