Ours are usually on the first Wednesday of the month, but we had a scheduled one this week on Thursday and it scared the shit out of me.

Interesting We have tsunami sirens on Wednesday here on the pacific coast
We test every first Monday at 11am, but after the siren, there's a voice saying that it's a test, broadcasted over the entire city. It was pretty eerie the first time I heard it.
Nah just check the time, if it's noon you're good. If it ain't noon you check the news and make sure it isn't a scheduled one at 10am for some test because they're planning to replace the sirens with new equipment. If it ain't that because the internet's out then it's probably real but if not you got a moment to see if it's real for another reason
If I'm an ambitious tornado, I'mma touch down exactly at Noon on Wednesday. Y'all'n't seen that coming didja?
I legit think that every time I hear it "if I was a tornado thisd be when I'd do it tell ya hwhat"
Start by checking the weather outside. If it's sunny and clear, no tornado. If not, start looking - places I've been at least, they've been reluctant to test if there's even much cloud coverage.
First monday of the month for my area
A similar thing applies for Sweden, where there's a quarterly test of the public emergency warning system, which always happens at 15:00 on Mondays.
The system has the nickname "Hesa Fredrik" ("Hoarse Fredrik").
Since this system will be used in case of an attack in the event of a war, this means we have to contemplate if Russia is attacking or if it's just Monday each time we hear the signal.
growing up near SAC bases like barksdale... second saturday of every month started with them testing the END OF THE WORLD sirens. if this siren went off any other time than a second saturday, kiss your ass goodbye, multiple megatons are incoming.
