Is it normal i never knew the months have the same number of days every year?

So you'd never looked at a calendar or timetable in your entire life????

NEWS FLASH for you. Turns neither Santa Claus or the tooth fairy are real, just in case you were wondering!

It is not normal. I don't know your age but you said you have a fiance so you are old enough so you should know this. How could you possibly go all these years and not know this? Have you ever made plans, looked at a calendar. Why should you be taught this anyhow. At some point, you should have learned the number of days in a month on your own. Maybe I can understand you not knowing the number of days in each month but to not know that each month has the same number of days, except February, is beyond ridiculous.

And every 4 yrs Feburary has 29 instead of 28, too. We call that a "leap year". And here's a little trick my grandpa taught me years ago.
Make a fist, and starting on the 1st knuckle is Jan. Then count each month to the pinky, then jump back to the first knuckle. Each month that lands on a knuckle has 31 days in it. Like Jan 1st knuckle, then Feb is between 1st and 2nd knuckles
1.2.3.4 5.6.7
1=JAN CLOSEST KNUCKLE
.=FEB
Where 4 is pinky knuckle and 5 is index finger.

Jan, Mar, May, July, August, Oct, Dec all have 31 days.

If you weren’t brought up with the “30 days hath September” rhyme I see why you would think this, honestly I probably would too.

I still have to say it to myself all the time.

You left off the end of the rhyme: Except for February which has 28 days clear and 29 in each Leap Year"

Don't forget Leap Year.... February has 29 days every 4 years...

A formula only scientists know 😂😂

Thanks, OP.

No

I learned this as a kid:

Thirty days hath November,
April, June, and September.
February has 28 alone,
And all the rest have 31.

That rhyme has been around since the 1500s. (Which explains why 'alone' and 'thirty-one' doesn't rhyme; they did the way the words were pronounced in in the 16th century.)

If you're not good at remembering verses, you can use the knuckle technique. If you count off the months on the knuckles and dips between them on your hand and then go back to the first knuckle when you get to July, the long-short pattern is perfect, and all you have to remember is that February is weird, with 28 days in three years out of four, and 29 days in leap years.

We get our calendar from the Romans. Their calendar was originally based on lunar months, but Earth's orbit around the sun takes a little bit less than 365¼ days, and the moon cycles through its phases in around 29½ days. This means the solar year can't be divided evenly into lunar months. The Romans recognised that their calendar drifted until it was out of sync with the seasons and they periodically added days to the year to adjust, but there was no fixed system for the adjustments. By the time Julius Caesar came to power, the calendar was more than two and a half months out of whack. After consulting with an Egyptian astronomer, he decreed that the year we now know as 46 BC would be 445 days long, and he introduced the pattern of months we use today. February is an odd month in being shorter than any other because the Romans considered February an unlucky month.

There have been additional minor adjustments over the centuries to take account of the fact that the solar year isn't exactly 365¼ days long, but Caesar's reforms are the reason why the calendar we use is known as the Julian system.
