the dawn of a new millennium

i have this coin "the dawn of a new millennium" but the date is 2001 .... i understood this to be a 2000 issued coin... what am i missing

There are 2000 and 2001 coins issues for the new millennium which began on Jan 1, 2001.
Year 2000 was not the new millennium dawn but the old millennium fall down.

The second millenium was completed on December 31st 2000. This is when the 1000th year of the 2nd millenium was completed.

The third millenium, therefore, started on January 1st 2001.

EDIT: We are now in 2020, but have note completed the year yet. It's only at the turn of 2020/2021 that 2020 years will have been completed (from the theoretical point "0" on which our calendar is based).

By the way, Canada got it all wrong in their 25¢ millenium issues. They commemorated 1999 and 2000, missing the most important year, 2001!

The year zero does not exist in the Gregorian calendar.

​You are missing that the millennium started on 2001, not on 2000 as many think wrongly.

To understand it, just think, you start counting from 1 to 10 , not from 0, so first number is 1 and last of first decade is 10, not 9. Therefore, first of second decade is 11, and so on.

One more clue: notice Krause Catalogs are 1701-1800, 1801-1900, 1901-2000.

​The year zero does not exist in the Gregorian calendar.

Indeed, and there cannot be a "year 0" because, when you start counting, you are in the first year until you complete about 365¼ days; at that point you not only complete year 1, but start the second year. So, you use ordinal numbers while you are in the year itself.

In law, when a bill was adopted in "Queen Elizabeth 1", it means in her first year as monarch, not that she had completed 1 year.

People look at the shape of the number and assume that because it starts with a 2 (2000) it means we are starting something new, while the mathematical beauty of it is that we're completing something... incomplete till then.

1999, December 31st at 24:00 = 0.999 of a millenium completed.
2000, January 1st at 24:00 = 0.9990027 of a millenium completed.

And what about the first year when it starts on 25th December ?

... 4 years after the person whose birth is being celebrated was actually born !!

Great knowledgeable responses- thx ..... so there are two of these coins issues .... one dated 2000 and the other, with same name, dated 2001...... yes.no

As usual, wiki helps : "25th dec. corresponds to the date of the winter solstice on the Roman calendar"
It's useful to understand that this date was instituted to thwart the pagan feasts of the winter solstice which took place all over the western europe of this era.

Wow ─ I now see that most countries got it wrong.

It's OK to celebrate the year 2000 as something special, but it's inaccurate to say it's the start of the new millennium.

By the way... Anyone knows what's special about the date November 19th 1999? This will never happen again in our lifetime. It will happen again only after over 1000 years...

​Only remember it was Thursday, and if it will happen again over 1000 years, most possible is a cosmic event... I will wait for the answer, so I'm ready when it happens next time.

Actually, not really an event.

A hint: It matters that November is the 11th month of the year, not the 12th.

​You're making me think... if not a cosmic event, and matters the ordinal of the month, maybe a calendar math.

11/19/1999=> 11191999 only 2 digits used and 4 of each, but Feb. 2nd., 2020 will be 02022020, only 2 digits, 4 of each and also radar., it would happen within our lifetime.... is not that. and is the same for French and English date formats.

Only I can see is 1 year, 1 month and 11 days till end of millennium, does not make sense...

Those are great observations, but it's actually much much simpler.

​ How about they all begin with the same letter ?
November
Nineteenth
Nineteen
Ninety
Nine

Wow! Never noticed that! But I don't think that will happen again in over 1000 years since a 5 T sequence is impossible (we'll be in the Three thousands then).

Note that, by the same logic as what I'm trying to have you guess, days like February 2nd 2000 happen quite regularly.

But, again, the fact that my little number pattern won't happen for over a 1000 years is nothing to make you despair of life. It's really a trivial little thing, though some mathematicians have looked at the pattern of occurrence of such numbers.

It will happen again on Nov. 11th, 3111?

​My first thought was "the last date that did not include a 2", but that would actually be November 30th, 1999.

November 19th, 1999 was the last date not to include a 2 or 0 until January 1st, 3111.

In fact, that is the last date in our lifetime where will not be a even number in the date.

Цитата: "adanieluy"​In fact, that is the last date in our lifetime where will not be a even number in the date.

​Yasss! Until January 1st 3111 (3111-1-1 the "0" in "01" is just a convention to fill two spaces), all dates will include at least one even number.

So, you have a lot of odd numbers, then none whatsoever for quite a long stretch, then a lot of them again... I'm sure there's a mathematical equation to represent that.

So, Feb. 2nd., 2000 was the first time in our lifetime there was no odd digit in date (if we agree "0" is not odd, cause some support "0" is not even nor odd).
