In my elementary schooling my parents would somewhat regularly (once a year, sometimes more) take a week or two vacation that didn't align with breaks, since sometimes things like family events, or good opportunities don't align with school. But my parents did it because they knew I wasn't really missing much. I and a good many others in my classes were WAY ahead of the curriculum already, and basically sitting bored in class all day. I remember my parents literally asked my teachers to give me more advanced homework because I would constantly say I learned basically nothing or that days would go by wasted reviewing things I had already mastered. So they were confident that I wasn't really missing much from being out even for a week or two at a time. I don't know if this is standard practice nowadays, but I know my parents also requested from the teacher that weeks worth of coursework so I could do them even while on vacation. I could usually finish a weeks worth of coursework within like an hour or two of sitting down, and I didn't even consider myself a particularly gifted student compared to some.
