dBan
+5.8 dBan

NASA’s catalogue records at least one partial or total lunar eclipse somewhere on Earth in 79 of the 100 calendar years from 2001 through 2100.

Calculation

p = 79 qualifying years / 100 years

Assumptions

The count uses distinct calendar years in NASA’s catalogue. Partial and total eclipse types, including suffix variants, count. Penumbral-only eclipses are excluded, and visibility from any particular location is not implied.
