Stack Exchange now has more than 170 sites. Is there a way to know when those sites were launched?
I know I can download all dumps and figure it out, but is there any cheaper way to do so?
There are two ways I know of to do this.
Method #1: If you know the name of the site, then go to Area 51, search for the site, and the proposal will say in the top right corner when it graduated. Example:
This way does not work for sites that never had an Area 51 proposal, such as Meta Stack Exchange and Stack Overflow.
Method #2: Go to All Sites on stackexchange.com (it's easiest sorted by name so you can find the site you're looking for), and on the far right side it will show the age of the site in years and months.
