When do most high schools and colleges hold graduation ceremonies?

Hey all, trying to get a sense of the big picture here. I know it varies, but on average, when do most high schools and colleges hold their graduation ceremonies? Are they typically all around the same time, or spread throughout the year?

High school and college graduation ceremonies in the United States are typically held towards the end of the academic year, which is usually in the late spring. For high schools, these ceremonies often take place in late May or June, although this can vary depending on the school district and its respective academic calendar.

For colleges and universities, it's somewhat similar. Many institutions hold their commencement ceremonies in May, following the conclusion of the spring semester. However, it's also common to see graduations in early June, especially for colleges on the quarter system. Other colleges, particularly those with a significant number of students graduating after the fall semester, might also hold a smaller commencement ceremony in December.

Remember, these are general time frames and specific dates can vary from year to year and from institution to institution. The best way to find out about a specific school's graduation dates is by checking their academic calendar, which often posts key dates several years in the future.
