I bought a Cartier nail bracelet to celebrate the fifth anniversary of my blog. It's an investment piece, but it's simple enough to wear every day, and it's something that will last forever.

I would hope the first heartbreak anniversary is the only time you feel it, and then after that, you don't really even notice.

Introduced to this world in Llandyssul, Cardiganshire, Wales, November 14, 1843, I celebrated my first anniversary by landing at Castle Garden, in New York City.

I was invited by President Bush to come to the United States on the occasion of the 50th anniversary of the mutual defense treaty.

The most important part of the process of mourning is regularly reciting kaddish in a synagogue. Kaddish is a doxology, which Jewish tradition has mandated children to recite daily in a synagogue during the year of mourning for a deceased parent and then on the anniversary of his or her death thereafter.

We know from the material that was recovered from the bin Laden compound that bin Laden was looking at the 10th anniversary of 9/11 as an opportunity to strike yet again at the U.S. homeland.

To mark the 10-year anniversary of 9/11, I wanted to launch an FDNY shirt that pays tribute to the brave first responders who, like my father, risk their lives in the line of duty on a regular basis. All of the proceeds raised from the sale of the T-shirt benefit the New York Police & Fire Widows' & Children's Benefit Fund.

I have for some time urged that a nuclear abolition summit to mark the effective end of the nuclear era be convened in Hiroshima and Nagasaki on the 70th anniversary of the bombings of those cities, with the participation of national leaders and representatives of global civil society.

The chances of a reunion now are less likely. I was thinking of having a 40th anniversary of the band, but now they are really another band, so it's all a bit weird.

Presently, the Commission for Commemorating 350 Years of American Jewish History has been brought about to encourage and sponsor a variety of historical activities that advance our understanding of the American Jewish experience as it marks this milestone anniversary.

June 2005 is the five year anniversary of the debut of Battle Pope.

We can't forget what happened on May 4th, 1970, when four students gave up their lives because they had the American constitutional right of peaceful protest. They gave up their lives. And to sing that song in that spot on that anniversary was very emotional for us.

This year, as we celebrate the 230th anniversary of America's independence, please remember the symbols that are sacred to this country. Fly Old Glory high and show your respect and admiration for this great nation and the values we hold dear.

I don't feel guilty about the music I love. If you feel guilty about something you dig, then you should stop feeling guilty about it. One of my favorite albums to this day is the 10th anniversary ensemble cast of 'Les Miserables,' the ultimate cast recording, and it is still something I love listening to top to bottom.

And this year is going to be the 25th anniversary of the 17-0 team, the only undefeated season.

America's got a Darwin problem - and it matters. According to a 2009 Gallup poll taken on the 200th anniversary of Charles Darwin's birth, fewer than 40% of Americans are willing to say that they 'believe in evolution.'

The London games mark the 24th anniversary of my winning two golds and setting the world record in the heptathlon. Someone is going to want it; records are made to be broken - it's only a matter of time. I hope mine will outlive me.

Last week, the House of Representatives passed a resolution honoring the victims and heroes of September 11th. As we commemorate the anniversary of 9-11, we must also remember that the threat is still very real today.

I didn't make my first solo record until 1981 so I don't have any 60's or 70's recordings but I am working on a large boxed set called DUST to be released next year, the 20th anniversary of my first solo record.

It is a matter of public shame that while we have now commemorated our hundredth anniversary, not one in every ten children attending Public schools throughout the colonies is acquainted with a single historical fact about Australia.

I feel there should have been some recognition of the Spice Girls at this year's 25th anniversary. We flew the flag for Britain around the globe in the 1990s and we achieved a hell of a lot.

I was always very grateful to 'em and am grateful to 'em now. I went back a couple of years ago and did their 20th anniversary show. But the longer I stayed on Hee Haw, the worse things got for me musically.

I think when I first realized that something interesting had happened was probably in 1994. There was a 25th anniversary of the ARPANET celebration and... somebody asked the question, 'Where did email come from?' I remembered that I had done this little program back in 1971. People looked back and nobody could find anything that predated it.

Perhaps a hundred people assembled one evening, May 15, 1876, at the time when the country was celebrating the hundredth anniversary of its political independence.
