The federal deadlines that decide whether you keep coverage or a benefit, counted from a date you set.
Open the Enrollment & Appeal Windows tool →These are the numbers on this site with the sharpest edges. Miss a COBRA election and the coverage is simply gone. Miss the Medicare Part B special enrollment period and you pay a late-enrollment penalty for as long as you have Part B. Miss a fair-hearing request and the decision stands, whether or not it was right.
So every date here is counted from a date you set, not from the moment the page loaded. That is deliberate: it makes the result reproducible, it shows the clock rather than hiding it, and it lets you check what a date will look like next week without waiting for next week.
One distinction matters more than any single number, and summaries routinely lose it. Most of these windows are floors — a plan or an agency may give you longer, and may never give you less. The Medicaid fair-hearing period is not. The rule gives a state a reasonable time "not to exceed 90 days," which makes 90 days the most your state has to allow, and reading it as a guarantee is exactly how someone misses it. The page says which kind each one is, in words, under the clock.
Where the states set the clock themselves, most of all for unemployment appeals, no number is shown. There is no federal figure to show, the states differ widely, and a plausible-looking default would be worse than a pointer to your own notice.
