Birth record and target date

Enter the recorded local birth time, birthplace coordinates, and the historical UTC offset in force at birth. Then choose a target local moment and its own offset. The editable example uses Manila.

A known birth time is needed for a precise age factor and derived Moon or angles. Check the birthplace and time-zone guide before interpreting a boundary degree.
