Sorry, something has gone wrong. Trending Now. Answers. Best Answer: Period means Pay Period which is the amount of time you work before getting paid - in your case it is 2 weeks. Period to date is a bit confusing, but it usually means the amount of hours you worked in the pay period covered by the check. If you quit in the middle of the pay period, your period to date would end at the day you quit. You worked the entire 2 weeks, so you don't really have to worry about that. Bi-weekly means every 2 weeks.
