Build the cusp figure

Source, figure & paper working

Increasing zodiac longitude runs counterclockwise from the ASC at the left. House spans follow the actual cusps; MC is placed at its measured longitude.

Twelve paper cusps · from C11

C11 records six opposites. Each opposite pair supplies both boundaries; the southern sign reversal is already included.

A reference wheel helps you compare your drawing. Exploring it never checks the paper drawing for you.

Part ATime

Line	Operation and rule	Working	Result
A1	Birth date, civil
A2	Clock time, 24-hour
A3	Summer time in force?if Y subtract 1h · older war time may be 2h · stated on the bench
A4	Standard time = A2 − A3
A5	Zone offset from GreenwichWest add · East subtract
A6	Universal Time = A4 + A5if 24h or more subtract 24h and move A7 forward a day · if below 0 add 24h and move A7 back
A7	UT datemay differ from A1 · every plate row is read on this date

C4	Latitude rows bracketing the birth: lower, upper; fraction gtable rows are 1° apart
C5	11 12 ASC 2 3 as columns: at the lower latitude, at the upper latitude, then by ga column that looks unlike its neighbours is the column with the mistake
C10	Southern? Reverse every sign on C3 and C5degrees and minutes unchanged
