An academic year typically spans from early fall to early summer, with two or three months of summer vacation marking the end of year. K-12 public schools generally observe local, state, and federal holidays, plus additional days off around Thanksgiving, the period from before Christmas until after New Year's Day, a spring break (usually a week in April) and sometimes a winter break (a week in February or March). Two or three days per year are sometimes devoted to professional development for teachers, and students have the day off.
Most colleges and universities divide the school year into two semesters. The fall semester often begins the day after Labor Day in early September and runs until mid-December. The spring semester typically starts in the middle or end of January and runs until May. Winter and summer classes might be offered in January and May–August. Major federal, state, and local holidays are often observed, including the day after and usually before Thanksgiving. Spring break is usually a week in March or early April, and in college party culture traditionally involves a warm-weather trip.
Unscheduled weather-related cancellations and emergency cancellations can also affect school calendars.
When taking summer school or summer camp schedules into account, the Independence Day holiday on July 4 is usually a scheduled holiday observance for which the summer program closes.

We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version.
