Number of Days between Passover in 622 BC and Passover in 2033 AD

A question came up on New Open Forum regarding the number of days between Passover in 622 BC & Passover in 2033 AD. The number of days is 969,352.799 (could be rounded off to 969,353). Therefore the actual number of days between Passovers would be 969,353 +18 days = 969,371 total days.

Formula for calculating is below (note: to arrive at March 26th day in 622 – followed same formula from known date of first Passover in 1447 BC).

PASSOVER MARCH 26th, 622 BC TO PASSOVER IN 2033 AD

From March 26, 622 BC until March 26, 2033 AD = 2,654 years

2,654 x 365.2422 = 969,352.799 days

969,352.799 days divided by 29.530588 (length of lunar month) =32,825.3809 months

The number after the decimal must be converted to days in order to know when the Passover will take place in the year 2033.

To convert .3809 to days we must:

Multiply it be the length of a lunar month:

.3809 x 29.530588 = 11.248201

Next, we minus this number from the number of days in a lunar month:

29.530588 - 11.248201 = 18.282387

Again, Passover in 622 BC began March 26th, and in 2033 AD it would begin 18 days (rounding off 18.282387) after March 26th, which would make Passover on April 13th, 2033 AD. And Passover day April 14th.
