−6 + 39 = 33The inclusive count is forty. AD 33 is the symbolic label, not the calendar date of an infant presentation.
The traditional calendar count runs from December 25, 1 BC through February 2, AD 1. Its symbolic labels run from 7 BC through AD 33. In both displays, birth to circumcision spans 7 elapsed units and circumcision to the fortieth-day marker spans 32: 7 + 32 = 39. The inclusive count is 40.
February 2 is derived as the fortieth-day marker of this chosen example. Luke does not supply that civil date or the exact presentation hour. AD 33 here is a symbolic coordinate label. Comparison with the preferred AD 33n Passion center is typological; AD 30n remains a possible Passion state.
