The Magic and Mystery of May 20 Sun, Pleiades at the Zenith

Each year around May 20 in the current era – the Sun and Pleiades come together as they cross the Zenith point (meaning they are directly overhead) at 20 degrees North Latitude at high Noon.

This is a time the Mayans called the “Days of No Shadows” because no shadows are cast when you have a straight stick in the ground or a person standing perfectly straight. There are no shadows cast by the pyramids either…

The Sun and Pleiades together on these days happens for about 144 years every 26,000 years. It is happening NOW!

A 12 minute visual explanation on the Solar Zenith


  1. Cayelin,
    Thanks so very, very much for your video on the Solar Zenith Days and the most informative article. This information is likely the most significant and important that I have read on your site. To know that the Mayans constructed a solar clock accurate to 26,000 years and to know there are other sites around the world that act as solar clocks is truly amazing! The photos and documentation were excellent. Wonderful to see you actually standing at one of those pyramids in Mexico. Wishing you many blessings this year and always!!!

    • Thank you so much Bruce. So glad you found this significant and important because of course I do too! For me it further inspires our deepening connection to Great Mystery. Joyous Magical Blessings to you too!

  2. Aloha Cayelin! I now live on the island of Hawaii and there are so many things that are new to me, but this is one of the highlights so far. Instead of just one solar zenith in a year, we have two! I found the following information on the Bernice Pauahi Bishop Museum website and wondered if you knew about this since I know you have traveled here for some workshops and so on in the past.

    Lāhaina Noon

    In the tropics (between latitudes 23o 26′ N and 23o 26′ S) the Sun passes directly overhead twice during the year. On these two days, at local noon, the Sun will be exactly overhead and an upright objects such as a flagpole will have no shadow. This phenomenon only occurs in the tropics; the Sun is never overhead in any other part of the planet. The northern reaches of the Hawaiian Islands, such as Midway Island, are north of the tropics and do not experience the overhead sun.

    The “overhead sun” date varies depending on how far north or south you are in the tropics. Thus, for Līhu‘e on Kaua‘i, this occurs on July 11, at 12:43 p.m. Farther south, on the island of Hawai‘i, the overhead sun date occurs on July 24 (12:27 p.m. for Hilo, 12:31 p.m. for Kailua, Kona).

    Here in the Islands a term we often use for zenith noon is Lāhainā Noon. This is a modern term, selected by Bishop Museum in a 1990 contest held to select a name for the zenith noon phenomenon. The term “Lā haina” means cruel sun in Hawaiian, and while the sun in the Islands is almost never cruel, it can be pretty intense as it shines directly down from the zenith.

    The chart below gives the overhead sun dates and times for several locations.
    Līhuʻe May 31, 12:35 p.m. July 11, 12:43 p.m.
    Haleʻiwa May 28, 12:30 p.m. July 14, 12:38 p.m.
    Kāne‘ohe May 27, 12:28 p.m. July 16, 12:37 p.m.
    Honolulu May 27, 12:29 p.m. July 16, 12:38 p.m.
    Kaunakakai May 26, 12:25 p.m. July 17, 12:34 p.m.
    Lāna‘i City May 24, 12:25 p.m. July 19, 12:34 p.m.
    Lahaina May 24, 12:24 p.m. July 19, 12:33 p.m.
    Kahului May 24, 12:23 p.m. July 19, 12:32 p.m.
    Hāna May 23, 12:21 p.m. July 19, 12:30 p.m.
    Hilo May 18, 12:17 p.m. July 24, 12:27 p.m.
    Kailua, Kona May 18, 12:20 p.m. July 24, 12:31 p.m.
    South Point, Hawai‘i Island May 15, 12:19 p.m. July 28, 12:29 p.m.

    • Thank you Georgia for these details and so great to know you are living on Big Island.

      AND Yes Hawaii is in the zone where there are two Solar Zenith Days (something I mentioned in the Video) and I love that you included the different ones around the islands at slightly different latitudes as that helps everyone see how this shifts due to latitude. I have heard of the Lahaina Noon but have never been there to witness it. One of these days it will be worth while to plan to be in Hawaii during a Solar Zenith.

      I wonder if there are any sights you know of that were built to track the Solar Zenith? If you find out about any let me know.

      The only places that only have one are at the extreme boundaries of 23.5 North or South of the Equator because the Sun is only at that declination during the Cancer or Capricorn Solstice. 🙂
