2025 Day 13: Day of the Moon

2025-0113M-2048 Austin, TX

Day 13 of 2025 is a Monday – day of the Moon. I’m actually writing this on Day 14, because it’s after midnight. That’s synchronistic because it’s a full moon now, which roughly marks Day 14 of the lunar cycle. Before writing, the full moon would be a multiple of 7 day and would be a day of rest and inner reflection. There would be no war. No harsh judgments.

But this blog is for Day 13. Like the number 7 of the ancient Babylonian times, the number 13 has some superstition surrounding it. The numbers 6 and 12 are considered complete. 7 and 13 disrupt the harmony of 6 and 12. They both represent excess, irregularity, transition, imbalance, and uncertainty. Many ancient cultures associated these numbers with misfortune. Divisibility of numbers was associated with harmony. Prime numbers like 7 and 13 have no divisibility except by 1 and itself. There are 13 full moons in a year which disrupts the natural alignment of the lunar year with the solar year. Today is Day 13 of 2025 and also a full moon.

The year 2025 is highly divisible with the divisors: 1, 3, 5, 9, 15, 25, 27, 45, 75, 81, 135, 225, 405, 675, and 2025. Last year 2024 had the divisors: 1, 2, 4, 8, 11, 22, 23, 44, 46, 88, 92, 184, 253, 506, 1012, and 2024. In 23 years when it is NYE before the year 2048, AI robots and such will be having a celebration like it’s 1999. Excluding 1, the divisors of 2048 are all multiples of 2: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, and 2048. So in computer binary numbers, the year will be 100000000000. This is  2^{11}, a single bit set at the 12th position (starting from the right). Ahhh … completion.

Diving Deeper: Mondays are synonymous with Days 2, 9, 16, and 23 and were transitional days in the lunar cycle. While not as prominently mentioned as the quarter phases, they had significance as moments of adjustment and preparation:

• Day 2: Early waxing crescent, symbolizing growth and refinement of new beginnings.

• Day 9: Momentum toward the first quarter, a time for strengthening and evaluating progress.

• Day 16: Waning after the Full Moon, focusing on balance and stability.

• Day 23: Waning crescent nearing the last quarter, symbolizing preparation for endings and consolidation.
