Explore the world of the Mayan calendar — and keep a beautiful day clock for everyday curiosity. StelaClock is a modern rebuild of the classic Mayan-inspired clock: a living Tzolk’in wheel for today, Long Count and Haab alongside it, and a Gregorian → Mayan date converter. Educational and contemplative — not fortune-telling. No account. No subscription. Everything runs on your iPhone. TODAY — YOUR LIVING CLOCK • See today’s day sign, tone, and glyph on a multi-ring Tzolk’in wheel • One-line energy for the day — gentle reflection, not a full reading engine • Current Cycles show Long Count place values (bak’tun · k’atun · tun) in progress • Day tones use classic bar-and-dot Mayan numerals • The highlighted kin (sign + tone) changes once per local calendar day at midnight • The gentle wheel spin is decorative only — hours and minutes do not advance the calendar CONVERT — ANY DATE • Pick a Gregorian date • Instant Tzolk’in (sign + tone), Haab, Long Count, and Calendar Round • Copy or Share results for notes, travel, or study • Convert historical dates too — including milestones such as the bak’tun completion of December 21, 2012 — as calendar history, not a live countdown EXPLORE — MOVE THROUGH THE CYCLE • Step day by day or jump ±13 (Wavespell) and ±260 (full Tzolk’in round) • Ring, timeline, and grid views of the same selected date • Optional Haab and Long Count labels, plus why the date matters (trecena, year bearer, night lord) PROFILES — LIGHT & LOCAL • Save up to 30 people with birth dates • Birth signature, upcoming alignment / return days, and optional mood history • Data stays on your device PRIVATE BY DESIGN • No login, no cloud account, no ads SDK • Optional daily reminder via Apple’s local notifications (you choose the time) • Themes: Mystic, Minimal, and Stone FOR LEARNING AND REFLECTION StelaClock uses classical Mayan calendar math (GMT correlation 584283). The Long Count uses the Maya’s modified base-20 (vigesimal) place values — shown as readable cycle fields, not a digital hours-and-minutes wall clock. Results can differ from other apps or traditions. Content is educational and entertainment — not medical, financial, legal, or professional advice, and not a substitute for living cultural teaching. Apple Watch and widgets are planned for a later update — not included in this release.
