Dates are approximate mean-lunation estimates. A production astronomy release requires comparison against a trusted ephemeris before claims are strengthened.

Schedule accuracy

Hourberry derives approximate full-moon instants from a mean synodic month. Reference certification checks expected phase/day agreement; use the result for general planning rather than observatory-grade ephemeris work.
