Once every two weeks en
Biweekly refers to an event that occurs every two weeks. There are fifty-two full weeks in a year of twelve months, making for a possible 26 biweekly events in a year. This is a greater number than if such events were held twice a month, because most months have more than four weeks. Wikipedia [ - ]
- A biweekly event occurs every two weeks. While "biweekly" is colloquially used, sometimes, to mean twice a week, it should only be used to mean every two weeks to ensure consistency of data. Events that occur twice a week should use "semi-weekly" instead.
