semestra
A semestra is a unit of time used in some academic institutions, typically representing a half-year academic term. It is derived from the Latin word "semestris," meaning "six-monthly." The academic year is usually divided into two semestras, often referred to as the Fall semester and the Spring semester. Some universities may also incorporate a summer term, which can be considered a separate session or a shorter, optional semestra.
The duration of a semestra can vary but generally spans approximately 15 to 17 weeks of instruction.
