Calculate the progressed Julian Date for secondary progressions.
Julian Date of birth
Julian Date to progress to
Progressed Julian Date
Secondary progressions: 1 day = 1 year Progressed JD = Birth JD + (age in years × 1 day)
// Age 30 = 30 days after birthconst progJD = getProgressedJD(birthJD, targetJD);// progJD is birthJD + 30 (if age is 30) Copy
// Age 30 = 30 days after birthconst progJD = getProgressedJD(birthJD, targetJD);// progJD is birthJD + 30 (if age is 30)
