The left-hand column shows the days in April and May, with their weekdays, and the days of Israel's first month.

Viewing the day of Christ's Birth in 1 BC (October 29th) as reckoned from the evening of October 28th, it will be found that the 7th month of His 34th year of 354 days ran concurrently with Israel's NISAN in AD 33.

Therefore, when Jesus came to Bethany 'six days before the (Jews') Passover' it was on the 9th of this 7th month, and in the evening Mary anointed Him with her ointment.
