List of New York City historical anniversaries

A number of New York City historical anniversaries have been commemorated as civic events by centennials and at similar landmark dates.

Several of these could be considered founding myths of the city, though there have been disagreements on when it was actually "founded".

Sometimes these anniversaries have occasioned major celebrations, and sometimes not.
