How come archaeologists don’t unearth treasure troves of relics from the beginning of Christianity at times other than Christmas and Easter?
Are you joking? The stuff is constantly being unearthed. If you travel to certain places, you’ll find that there are digs going on all the time; I have seen such in Turkey, Greece and Italy. The news hits at certain times but the work is ongoing.
Most of your peer review journals as well as popular science/history periodicals are published FOUR TIMES PER YEAR at roughly equal intervals.
There's a USPS rule regarding the minimum number of times you need to publish to be recognized as a Periodicals Class publication entitled to the lower Periodicals Class rates of postage.
That minimum number of times is FOUR. It's been in place for over a century!
So, publish in December ~ then publish in April ~ then publish in July ~ then publish in September ~ you are hitting some peak times in America's public life ~ to wit: Christmas, Easter, Mid-Summer and Fall Semester/Harvest. This is a very popular schedule particularly since you can expect your readers to have some Holiday Free Time to read your publication. With that seasonality in place it's a logical step to do the Bible/Rome/Greece stuff in December. Other related materials gravitate around the other holiday periods.
