Moon Phases Visible from Taipeh

From Taipeh at latitude 25.0°, the moon's appearance follows the same 29.53-day synodic cycle visible worldwide — all 8 phases from New Moon through Full Moon and back. However, Taipeh's mid-latitude latitude affects the moon's maximum altitude in the sky. The moon can reach up to 93.6° altitude when crossing the meridian near summer solstice, and only 36.4° near winter solstice. This seasonal variation determines how high the moon appears above Taipeh's horizon and affects lunar photography planning.

Taipei liegt nahe des Wendekreises des Krebses auf 25°N — dem Breitengrad, an dem die Sonne zur Juni-Sonnenwende genau 90° Höhe erreicht und zur Mittagszeit keinen Schatten wirft. Das Nationalmuseum für Naturwissenschaften der Stadt betreibt ein spezielles Sonnenobservatorium, das den Zenitdurchgang der Sonne verfolgt, und das Wendekreis-Wahrzeichen in Chiayi zieht jedes Jahr im Juni Tausende Besucher an, um das 'No-Shadow-Day'-Phänomen zu beobachten.

Moonrise & Moonset Times at Taipeh

The moon rises approximately 50 minutes later each day as seen from Taipeh. This daily delay occurs because the moon orbits Earth eastward at about 1 km/s, moving roughly 13° per day against the background stars. At Taipeh's latitude (25.0°), the moon's rise and set positions along the horizon shift seasonally — rising further north in summer and further south in winter. MoonSync calculates exact moonrise and moonset times for Taipeh using real-time ephemeris data.

Taipei auf 25°N erlebt einen relativ bescheidenen saisonalen Tageslichtunterschied von 3,5 Stunden zwischen Sommer und Winter — der geringste unter den ostasiatischen Hauptstädten. Diese Äquatornähe bedeutet, dass die Goldenen Stunden der Stadt das ganze Jahr über konstanter sind als in höheren Breiten, wobei die Sonne in steileren Winkeln auf- und untergeht und klare, dramatische Schatten in Taipeis enger Gassenkultur erzeugt.

Moon Illumination & Taipeh's Dark-Sky Planning

For stargazing and astrophotography in Taipeh, moon illumination percentage is the critical number. A Full Moon (100% illuminated) washes out all but the brightest stars and makes deep-sky observation nearly impossible. The 7 days around New Moon (0-15% illumination) provide the best dark-sky window. At 25.0° latitude, combine moon phase with the Twilight Calculator to find nights when both astronomical darkness and minimal moonlight coincide — these 'astrophotographer's golden hours' occur roughly once per month at Taipeh.

Lunar Data Accuracy for Taipeh

MoonSync computes moon phase, illumination, moonrise/moonset times, and lunar age for Taipeh using real-time ephemeris data. Phase illumination is accurate to ±1%. Moonrise and moonset times are calculated from Taipeh's precise coordinates (25.0°, 121.6°) and corrected for atmospheric refraction. The Keplerian orbital model used achieves timing accuracy of approximately ±30 minutes over a synodic month. For sub-minute lunar event timing, consult the USNO Phases of the Moon data service.
