About this result
The calculation uses noon UTC. If the Moon crossed a phase boundary during the date, a result calculated for a specific local birth or observation time may use an adjacent phase name.
Some people associate the First Quarter with decision, action, and meeting resistance. This symbolism does not establish effects on personality, health, fertility, behavior, or outcomes.

Frequently asked questions
Why is this page noindex?
Date results remain shareable, but excluding arbitrary dates from search prevents a vast collection of thin, repetitive pages.
What does moon age mean?
It is elapsed time since the preceding astronomical New Moon, not the geological age of the Moon.
Was this phase the same everywhere?
At the chosen instant, yes. Orientation and whether the Moon was above the horizon depended on location.
