Here’s an excellent article, EXACTLY on point of our discussion. It is NOT written by a SDA, but it does quote Leroy Froom (SDA) and his supporting article.

The BIBLICAL PROPHETIC YEAR ITS LENGTH, ORIGIN AND APPLICATION
ZIONS TOWER of the MORNING TRACT PUBLICATIONS P. O. Box 28021 Detroit, Mich. 48228 1983

From the Conclusion:

In approaching the biblical prophetic year, the first task was to define its length, as determined by a comparison of related Scriptures containing similar time expressions. By subjecting these to a formal mathematical reasoning process, it was found that the prophetic year was equivalent to 360 days, and the prophetic month to 30 days.

The next inquiry, almost a parenthesis to the study, was to probe the origin of these lengths; that is, to consider how the Creator might have decided upon employing a 360-day year and a 30-day month for use in biblical prophecy. The conclusions, of course, could only be suggestive, since they are not positively stated in the Bible. Nonetheless, in correlating Scripture with naturally recurring motions of the sun, earth, and moon, certain relationships were evident. An average of the solar and “lunar” years yielded 359.80 days, and of the Gregorian and Jewish months, 29.98 days, almost identical with the prophetic 360-day year and 30-day month.

Why would you need a prophetic year? God’s word and his creation are in perfect harmony. In fact we are told to look at creation to understand invisible things. In order to keep spring near the vernal equinox, every calendar has adjustments that must be used. Our years are not all the same length. God determined the length of a day, a month and a year when he put our solar system in motion. We know exactly how long each one is , we do not need to average various errors to find out

There is purpose in everything God does. You will never discover why God used the ratios that he used because you must have a 30 day month and a 360 day year to promote your error.
