To answer the three different interpretations of your comment.

Kagi is beholden to your dollar, not ads. If they suck, people leave. Google is not beholden to your dollar, they are beholden to ad dollars.

The other comment explained the interface, but they date via crawl date. A web crawler found it on that date, so it sprang into existence on that day.

It’s an absolute mystery how a trillion dollar is fucking up badly enough to eat into its monopoly, I agree.

Kagi has a time filter right in the search to choose past year, two year, etc. I believe. I’ve definitely used the past year before.
