Hi everyone. How Many Days answers one question: how many days of supplies do governments actually tell households to keep?
The answers vary more than you'd expect. Most that give a number say three days, a few say a week or more, and some give no number at all. They're also easy to misquote, because a whole-home reserve, a grab bag and a figure for one hazard often get treated as the same thing.
So the site keeps those apart. Each of the 67 entries links to its source and records what changed and when. Most recent activity simply repeats an existing figure, and the change log says so rather than calling it an increase.
There's also a planner for water and food, and a stress test that shows what would run out first in your home.
If you spot a figure that's wrong or out of date, please use the "Send a correction" link, or tell me here. I'd rather fix it than leave it up.
