Lunascope – Moon Phase Calculator

The procedure on the Nightly Lunascope panels gives a good approximation of your Birth Lunar Phase. However, due to some strangeness in the modern Gregorian calendar, it may be off by a day or two. The following calculator gives a more accurate result.

The Nightly Lunascope and this page, are works in progress. Please come back to check out new features.
