The Block Calendar is designed for those looking to improve productivity through a more rhythmic and predictable approach to strategizing their life. I would like to introduce the 2026 Rainbow Block Calendar: Roy G Biv Edition.

In this system, holidays and observances are easy to reference, and circles represent full moons.
The Rainbow Block Calendar follows the ROY G BIV color-coded system for the seven-day week:

Toonuppasog, or "Time Turtle," a Native American lunar-based counting system. This method utilizes the anatomical structure of a turtle shell to track time, reflecting traditional ecological knowledge that connects nature with the passage of time.
Key features of the Toonuppasog calendar include:
- 13 Moons: The 13 central scutes (plates) represent the lunar cycles within a single year.
- 28 Days: The 28 smaller surrounding scutes correspond to the number of days in each lunar month.
- Calculation: These 13 cycles of 28 days total 364 days.
This system serves as a visual and spiritual guide for tracking environmental changes and cultural ceremonies, as noted by the Museum of the Cherokee in South Carolina.

How long is Daylight Saving Time? We can answer that using the Rainbow Block Calendar.
The Rainbow Block Calendar provides a visual map of the fifty-two week year, organized into four-week blocks of twenty-eight days each. In this system, holidays and observances are easy to reference, and circles represent full moons. Using this map, Daylight Saving Time begins on Sunday of Week 11 and ends on the same day in Week 45. This spans 34 weeks (45 - 11 = 34), totaling 238 days (34 x 7).
Why the alphabet is important?
This Alpha Block Calendar also utilizes an alphabet-based number cipher. By pairing the letters A through Z with the week numbers, the year is clearly divided. The first half of the year uses capital letters, while the second half uses lowercase. Because "M" is the 13th letter, both "M" and "m" mark the year into four equal quarters of 13 weeks each.
The 2026 Block Calendar is your map to new perspectives and possibilities.

The Block Calendar is the to-do calendar for Ultra-productive people, and is a new way to game, plan and strategize your health, wealth, and well-being. The Block Calendar is simply a gridiron of 13 Blocks over the rolling 52 week playing field. A calendar year can be broken down into 13 – four week periods. Thus, you will have a 13 a period year (vs. a 12 period year with a monthly accounting system). With a 13 period year, holidays fall into the same week of the same period every year. With a monthly accounting system, your period can end any day of the week, and holidays can fall into different weeks in the same month of different years.
One block is 28 days or 4 weeks, or 2 bi-weekly paychecks, which happen like clockwork 13 times a year. Blocks have the simple advantage of being easier to work with than months, as months are of variable lengths and each block is always 28 days (4 weeks at a time) with 13 blocks per year. Holidays are in red; the week number that contains the first of each month is colored in blue.

The name the Block Calendar derives medical scheduling protocol where doctors and medical professionals training programs nationwide follow a 4 week or 28 day cycle. The 28 day block rotations cycled medical students from department to department evenly to rotate throughout the year. In practice, senior residents begin a week before the first year interns start for better continuity of patient care, and have an overlap of knowledge about patient history and information. The doctors were given a list of dates when each block started, but no “Block Calendar.”
From 1928 to 1989 the Eastman Kodak Company produced a Calendar which had 13 periods a year, clustered into 4 week or 28 periods from the advice of George Eastman President of Eastman Kodak Company. "I loved it," says John Cirocco, a former Kodak employee who worked at the company in the late '80s as a tech advisor. "It was a major piece of financial applications, and from a financial perspective it made the ability to compare sales periods a hell of a lot easier." The Kodak Calendar was printed on one page but was still broken up into blocks like months called periods. Simply said it’s a better metric to compare day to day operations with presion standard to regulate the income to debt ratio.
