I recently revived a small niche web tool I had left untouched for months:
It converts a Gregorian birth date into a Mayan Tzolk'in calendar reading.
The Tzolk'in is a 260-day sacred calendar cycle made from 20 day signs and 13 tones. The tool calculates a user's Nawal day sign, Galactic Tone, and a short reflective interpretation.
Why I came back to it
The project had been quiet for a while, but Google Search Console showed that people were still finding it through search.
Queries like:
- mayan astrology calculator
- mayan zodiac sign calculator
- mayan birth chart
- mayan calendar calculator
were still getting impressions and clicks.
That was enough of a signal to make me revisit the project instead of abandoning it.
What I added
The original version was mostly a single calculator. I expanded it into a more complete static tool site:
- A Mayan astrology birth date calculator
- A result page with Nawal and Galactic Tone interpretation
- Today's Mayan date
- A compatibility calculator
- A guide to the 20 Nawal day signs
- A guide to the 13 Galactic Tones
- SEO pages for related search intents
- A simple waitlist for deeper personalized PDF reports
The site is built with Next.js and exported as a static site.
The interesting part: waitlist validation
I wanted to test whether this could become more than an ad-supported content site.
Instead of building payments, accounts, and PDF generation immediately, I added a lightweight waitlist CTA on the result page:
Want a deeper personalized Mayan birth chart report?
When users click it, they are invited to email us if they want early access.
This is intentionally higher friction than a normal email input. If someone actually opens their email client and sends their birth date and result, that is a stronger signal than a passive signup.
Within a short time, a couple of users actually emailed us with their birth dates and Mayan signatures.
That changed the question from:
"Is this just a fun niche calculator?"
to:
"Is there enough intent here to justify a paid personalized report?"
Why I did not build payments first
It would be tempting to add Stripe immediately.
But for a niche tool, I think that would be premature.
Before building a full payment flow, I want to validate:
- Do users want deeper reports?
- Would they pay for them?
- What kind of report feels valuable?
- Does a PDF report feel trustworthy enough?
- What methodology explanation is needed?
So the next step is manual delivery: generate a few early-access PDF reports, send them to interested users, and ask for feedback.
Credibility matters
For a tool like this, trust is important.
The calculator part is deterministic: it converts a Gregorian date into a Tzolk'in signature.
The interpretation part is reflective. It is not scientific, medical, legal, or psychological advice.
For the PDF reports, I am adding:
- A methodology section
- A cultural note
- A clear distinction between calculation and interpretation
- A disclaimer
- A sample report structure
I think this matters, especially when working with cultural or spiritual systems. The goal is to be useful and respectful, not to pretend to be an official authority.
Tech stack
The current stack is intentionally simple:
- Next.js
- Static export
- Cloudflare Pages
- Google Search Console
- Google Analytics
- Plain HTML/PDF templates for early report samples
No database yet. No payment integration yet. No account system.
The project is still in the validation stage.
What I learned
A few takeaways from this small experiment:
- Old niche projects may still have search demand.
- Google Search Console can reveal what users actually want.
- A calculator can be more valuable than a blog post because the result is personal.
- High-friction waitlists can be useful when you want stronger intent signals.
- Paid product development should probably start manually before becoming automated.
Feedback welcome
I'd love feedback on the tool and the approach:
Specifically:
- Is the calculator flow clear?
- Does the result page feel useful?
- Would a paid PDF report make sense here?
- How would you improve trust and credibility for a niche spiritual/calendar tool?
Thanks for reading.
