What's the longest stretch of time you worked without a break or day off?

[Grant]

What would you say is the longest stretch of time you worked without a break of day off? I have always had to take a break from work, and I always need a day or two to recover from the work week. But, what about you? What is the longest you worked in a single instance? Like was it a full day? Maybe two days or longer? Or maybe you haven't stopped working daily for months.
