Red
20260812 mod 12 = 0 → Red.
Daily color calculator
From the date you build a YYYYMMDD seed, take modulo 12, and read a color from twelve slots. The same date always yields the same color.
Here daily color is a function of the date modulo 12. This tool is for entertainment and learning, not fortune-telling or life advice. It does not replace personal, medical or financial decisions. Also try daily tarot and the personal year number.
Result
Pick a date to see the daily color.
How it works
Daily color is deterministic calendar fun. From the date we build a YYYYMMDD seed, take modulo 12, and read a color from a twelve-item palette.
Formula: index = (year×10000 + month×100 + day) mod 12. The same date always yields the same color. There is no random draw or “day energy” outside the arithmetic.
Palette (indexes 0-11): Red, Orange, Gold, Green, Sky blue, Indigo, Violet, Rose, Turquoise, Silver, White, Amber. These are entertainment labels, not styling advice.
Example: 12 August 2026 → seed 20260812 → 20260812 mod 12 = 0 → Red. 15 May 1990 → 19900515 mod 12 = 3 → Green.
Another case: 1 January 2025 → 20250101 mod 12 = 5 → Indigo. 15 June 2024 → index 11 → Amber.
This is not the same as daily tarot (a card from a date seed) or the personal year (a 1-9 cycle from month, day and year). Daily color is the simplest modulo-12 map.
We do not use clock time, a name or a zodiac sign. The date alone keeps the result repeatable and easy to check on a calculator or on paper.
Treat the result as a day motif for fun or a creative workshop. Do not read it as fortune-telling, a mood diagnosis or medical or shopping advice.
Formula
seed = year × 10000 + month × 100 + day (YYYYMMDD as a number)
index = seed mod 12
color = palette[index] (12 fixed color labels).
How to use the calculator
- Type the value in “Date” using the unit printed on that label, not a different scale.
- Click Calculate or wait for the live result.
- Read the color from the 12-color palette.
- Use the examples to see different modulo-12 indexes.
- Read the result card beside the form and match it against an example that fits your case.
Suggested uses
- A quick color motif for a chosen calendar day.
- Practice modulo arithmetic on a YYYYMMDD number.
- Compare several dates and their 0-11 indexes.
- Creative workshop: color as a day label (entertainment).
- Confirm the same date always returns the same color.
- Pair with daily tarot as a second date motif.

Frequently asked questions
How is the daily color made?
We build a YYYYMMDD seed from the date, take modulo 12, and read a color from a fixed 12-label palette.
Is the result random?
No. The same date always yields the same index and the same color.
Which colors are in the palette?
Red, Orange, Gold, Green, Sky blue, Indigo, Violet, Rose, Turquoise, Silver, White, Amber (indexes 0-11).
How is Daily color calculator different from Daily tarot?
Daily tarot maps a date seed to a card. Daily color maps the seed modulo 12 to a color.
Do time or name matter?
No. Only the chosen calendar date is used.
What date format should I use?
Prefer YYYY-MM-DD, e.g. 2026-08-12.
Is this fortune-telling or style advice?
No. The calculator is for entertainment and learning. It does not replace shopping, medical or life decisions.
Why twelve colors?
Modulo 12 gives a clear, repeatable cycle similar to months or signs, without claiming a “cosmic” color.
What color is 2026-08-12 versus 2025-01-01?
12 August 2026 is red. 1 January 2025 is indigo. Seed from the full date, 12 colors, not a new roll on refresh.
Does a blank date roll a new color?
No. With no date the card stays quiet. Type 2026-08-12 to get red. This is not daily tarot.
