There is now a 3-day limit for the HNQ. But what was the longest amount of time that a question stayed on the HNQ for prior to that limit being instituted? I'd imagine some questions having stayed on the HNQ for well over a week.
The limit on a question's lifetime in the HNQ has always been limited to 30 days and this limit has recently been decreased to 3 days. So current records are impossible to break in the future, unless the policy changes again.
I've been scraping the HNQ multiple times per day since August 4th, 2018. While this is only a short period in the history of HNQ, these are the questions with the longest appearance in this period:

It's rather interesting that the top 4 (and #8) questions were posted during Winter Bash 2018.
