2026 Eclipse Season Guide
The 2026 eclipse story is a clean way to teach why lunar phase, node alignment and observer visibility are different parts of the same time calculation.
Eclipse seasons are not random sky events. They happen when the Moon is near an orbital node at new or full Moon, then local visibility and safety details decide what a person can actually see.
Story
The two-gate eclipse test
A solar eclipse needs new Moon timing near the lunar node. A lunar eclipse needs full Moon timing near the node. The first teaching gate is therefore phase; the second is node distance. Most lunar phases fail the second gate because the Moon orbit is tilted to the ecliptic.

Why 2026 matters
The 2026 total solar eclipse is a high-interest example because official maps and predictions can be checked against the educational phase/node idea. CalculationTime can explain the screening logic, then direct readers to NASA or other official sources for path, magnitude, timing and eye-safety details.

Use the Eclipse Calendar to explore candidate dates, the Eclipse Calculator to inspect phase/node closeness, and the Moon Phase Calendar to see why a new Moon by itself is not enough.
