A day is a 24-hour period, or the part of it when there is daylight.
Dictionary definition
Day can mean a complete 24-hour period, the light part between night and night, a particular date or occasion, a period spent at work or school, or an era in history. In astronomy, a day can be the time a planet or moon takes to rotate once, so not every world's day is 24 hours.
