Cach Kham Pha Moon Calendar 3D Explorer
The Moon Calendar 3D Explorer starts as soon as the page loads: drag to orbit the Moon, scroll or pinch to zoom, and slide the calendar day control from 0 to 29.53. Everything renders on your own device - no install, no account.
Open the scene
Load the page and the Moon appears in a calendar-style view with earthshine on the dark limb. The 3D engine downloads once and is cached. If WebGL is unavailable, a plain notice appears instead of a broken canvas, and the facts panel still reads normally.
Scrub the synodic month
Move the calendar day slider from 0.0 to 29.53. Day 0 is new moon; near day 7.4 you reach first quarter; near day 14.8 full moon; near day 22.1 last quarter. The panel updates the phase name on every move and the day label shows the selected value.
Play one full cycle
Press Play month to animate from day 0 through 29.53 and loop. At 1x one synodic month takes about 30 seconds. Press again to pause on any day for a closer look at earthshine or the lit fraction.
Toggle libration
Press Show libration to watch the Moon nod and rock through published ranges. Longitude wobble reaches +/-7.9 degrees and latitude +/-6.7 degrees - together they explain why about 59 percent of the lunar surface is visible over time. Press again to hide the wobble.
Read the facts panel
The panel lists synodic month 29.53 days, libration in longitude +/-7.9 degrees, libration in latitude +/-6.7 degrees, and 59 percent surface visibility - NASA published values. A note below states that on-screen Moon size is enlarged; the table numbers are real.
