It is the time around Lammas Day or August 1st. It was a kind of harvest festival. So when the nurse asks how long it is until Lammas-tide, she is asking how long it will be until August 1st. Mrs. Capulet says fourteen plus days (a fortnight is fourteen days, and she says it is a few days more than that). Juliet's birthday is Lammas-eve, which in the same way that Christmas Eve is the day before Christmas, is the day before Lammas day, i.e. July 31.
