nGeneTime

nGeneTime combines three complementary experiences: a kinetic desk clock, a solar-term-based perpetual calendar with Four Pillars (四柱), and time-based line casting for The Book of Change (周易). iPhone • Landscape: A kinetic desk clock with magnetic motion and hourglass-style disappearance effects that visualize the flow of time. • Portrait: A perpetual calendar with lunar dates, day pillars, current Four Pillars, solar-term transitions, date-selectable hour-pillar tables, and Zhouyi line casting. Home Screen widgets Three widgets provide calendar and pillar information without opening the app: • Calendar: The current month, lunar dates, day pillars, and the applicable solar-term boundary. • Four Pillars: The current hour, day, month, and year pillars. • Hour Pillars: All twelve hour-pillar intervals, with the current interval highlighted. Widget calculations follow the time zone and calculation mode selected in nGeneTime. Longitude correction is used when that mode is selected and valid location data is available. Solar-term-based year and month pillars Year and month pillars do not change at ordinary Gregorian boundaries. • The year pillar changes at the Beginning of Spring (立春), rather than January 1. • The month pillar changes at the applicable monthly solar-term boundary, rather than the first day of the Gregorian month. • Year-pillar information, month-pillar transitions, and the applicable solar term are shown on separate lines. • The local date and time of each solar-term boundary are displayed. • The solar-term boundary date is highlighted in blue and uses the standard green appearance when selected. Day and hour pillars continue according to their established calculation rules. Solar-term transition times follow the selected time zone, while longitude correction is applied specifically to hour-pillar boundaries. Longitude-corrected pillar time Standard clock time is based on a time-zone reference meridian. nGeneTime can apply a longitude-based correction relative to that meridian, providing a location-specific basis for determining hour-pillar boundaries. The Book of Change (周易) From the portrait calendar, open a full-screen line-casting interface and cast one line at a time. Each cast uses the hundredth-second value of the running timer: an odd value creates a whole line, and an even value creates a broken line. Six lines form a set, and multiple sets can be reviewed. This feature focuses on line casting and visual review. It does not reproduce a complete digital edition, translation, commentary, or interpretation of the Zhouyi. Apple Watch The companion Apple Watch app provides: • Current time and Four Pillars • Solar-term-based year and month pillars • Optional longitude-corrected pillar time when location is available • Monthly calendar with pillar information • Selected-date hour pillars • An integrated timer with immediate-start presets, custom durations from 1 to 180 minutes, remaining-time progress, and selectable single, double, or rapid vibration patterns • Circular and corner complications showing the current day and hour pillars; while the timer is active, the complication also shows countdown information and the remaining-time proportion Privacy Location access is optional and is used only to calculate longitude-corrected pillar time. Precise Core Location coordinates are processed locally. If Core Location is unavailable, the app may request an approximate IP-based location from a network service. No account is required. nGeneTime does not use information for advertising or cross-app tracking. nGeneTime presents traditional temporal frameworks through a clear, modern interface.
