For Americans, Saturday, Dec. 6, 1941, began as most Saturdays before it.

American life was different then; Saturdays were different because Sundays were different.

Sundays were not shopping days; they were more geared to rest and relaxation at home. Some families ventured away from home on that day of the week only to attend religious services or “to go for a ride,” if they were fortunate enough to own a vehicle.

Anyone interested in sports learned about game results either by way of a radio or waiting until the next publish day of their local newspaper.

Television was nowhere around, because the existence of television in homes would not begin “gearing up” for about a decade or so hence.

Transistor radios were years away and cellphones were decades away, so possessing a news source while on the go was virtually unheard-of. Even then, coverage of the news beyond what was available in newspapers was primitive.

The “electronic media” even were primitive, by today’s standards, on Nov. 22, 1963, the day President John F. Kennedy was assassinated in Dallas, Texas.

So, nothing was out of the ordinary when people shut off their lights for the night on Saturday, Dec. 6, 1941, most of them planning for nothing out of the ordinary also the next day, beyond perhaps a church service and family dinner.

Again, life was different then.

But rather than Sunday being pretty much uneventful, by the end of that day it would be anything but — for any American in touch in any way with the world outside of their favorite places within their home environment to spend part of their day.

The information about an alleged attack by Japanese planes on the U.S. naval base at Pearl Harbor, Hawaii, filtered in slowly at first, then spread more and more quickly as one neighbor told another and more and more people began turning on their radios to try to obtain more information and tried to find out whether it was truth or a “false alarm.”

Just over three years earlier — on Oct. 30, 1938 — Orson Welles and his Mercury Theater on the Air wreaked havoc on the lives of many Americans with his “War of the Worlds” broadcast about an alleged Martian invasion — especially among people who missed the beginning of the broadcast and were “greeted” instead with programming seemingly interrupted by reports of the alleged invasion.

“The War of the Worlds” still is regarded as the most famous radio broadcast of all time, but the incoming news about Pearl Harbor on Dec. 7, 1941, was not a cruel, albeit unintended, hoax, just like Sept. 11, 2001’s first reports about that day’s terrorist attacks — these accompanied by immediate video footage — were true to the core.

When the news really “sank in” about Pearl Harbor, many families realized that their lives were about to change, forever, and not for the better. Many families would lose one or more members in the fighting that would ensue against Japan and the other Axis powers.

The coming end-of-year holidays would give way to gearing up America’s war resources for the battles to come.

That effort would entail sacrifices, rather than emphases on one’s personal wants.

Dec. 7, 1941, was not just another day in history; with it came lessons that remain relevant even today.

Don’t be someone who ignores those lessons by failing to seek them out.
