Navigate with the Stars: The New Nautical Almanac for 2026

August 19, 2025

In an age of GPS and electronic charts, the time-honored skill of celestial navigation remains an essential art for mariners. It requires precision, knowledge, and a reliable guide. That guide is the Nautical Almanac, a critical resource that continues to serve as the standard for marine navigation. The new Nautical Almanac for 2026 is now available, providing the essential data needed for celestial navigation.

The Nautical Almanac is a powerful tool. It’s an annual treasure trove of astronomical information, published jointly by the U.S. Naval Observatory and the U.K. Hydrographic Office. This indispensable guide includes Celestial Body Positions: Accurate data for the Sun, Moon, planets, and stars. Rise and Set Times: Precise calculations for sunrise, sunset, moonrise, and moonset. Ephemeris Data: Detailed information on planetary and lunar positions. Together, these provide everything you need to plot your position on the open sea, ensuring you can always navigate confidently and precisely.

Beyond the Open Sea

While primarily a resource for navigators, the Nautical Almanac’s applications extend far beyond the maritime world. Amateur astronomers can use it to plan observations, track celestial events, and deepen their understanding of the night sky. Even for those with a casual interest in astronomy, the Almanac offers a fascinating look into the detailed movements of the cosmos. Whether on the water or under the stars, the Nautical Almanac connects you to the timeless art and science of finding your way.

Happy Birthday, U.S. Navy!

October 11, 2023

The United States Navy celebrates its birthday on October 13th each year. This date commemorates the day in 1775 when the Continental Congress authorized the purchase of two armed vessels to attack British ships during the American Revolution. This marked the beginning of the Continental Navy, which later became the United States Navy. In celebration of the many responsibilities of the U.S. Navy, we’re highlighting resources focusing on its role in scientific endeavors supporting military and civil water navigation safety.

The Astronomical and Nautical Almanac are jointly published by the United States Naval Observatory and Her Majesty’s Nautical Almanac Office in the United Kingdom.

The Astronomical Almanac is a comprehensive publication that contains data on a wide range of astronomical phenomena, including the positions of planets, moons, stars, and other celestial objects; the times of eclipses and other events; and information on the Earth’s rotation and motion. It is used by astronomers, navigators, and other scientists for a variety of purposes, such as planning observations, calculating trajectories, and understanding the dynamics of the solar system.

The Nautical Almanac is a subset of the Astronomical Almanac that contains the data needed for celestial navigation. It was first as part of the American Ephemeris and Nautical Almanac and then to provide the US Navy with a convenient form of astronomical data for celestial navigation. This includes the positions of the Sun, Moon, stars, and planets at specific times and dates. This book remains the standard resource for marine celestial navigation for the U.S. Navy and is still used today as a backup to GPS and other electronic navigation systems. Safety on the water is essential whether navigating on a “Dingey” or a massive Naval Carrier.

Here are some ways to celebrate the Navy Birthday:

  • Attend a Navy Birthday celebration at a local Navy base or community center.
  • Fly the Navy flag or wear a Navy shirt.
  • Learn more about the Navy’s history and heritage.
  • Read a book or watch a movie about the Navy.
  • Donate to a Navy-related charity.
  • Thank a Sailor for their service.

No matter how you choose to celebrate, take some time to honor the United States Navy on its birthday.
