Memory Beta, the wiki for licensed Star Trek content.

A month is a unit of measurement that denotes the passage of time. The Gregorian Calendar on Earth used months as a means to measure the passage of time.

Earth months are generally about four weeks in length. Most of the Earth month usually spans 31 days. The human months of April, June and September each span 30 days. February, which is the second month of the human year normally spans 28 days, except for every fourth year, in which case it spans 29 days.
