How long is the spring school semester?

The length of the spring school semester varies depending on the institution and the particular country. In the United States, the spring semester typically starts in mid-January and ends in late April or early May, with a break in between for spring break. The exact dates may differ from one institution to another. In other countries, such as in the United Kingdom and Australia, the spring semester may be referred to as the "spring term" and runs from January to May. Again, the specific duration can vary. It's important to check with the specific institution or educational system to get the precise dates for the spring semester.
