What does "until next week" means?
Today is Tuesday of Week 1.
My boss said she will be on leave today until next week.
(1) She will be on leave from Tuesday to Sunday of Week 1 and back on Monday of Week 2.
(2) She will also be on leave in Week 2.
Which one is correct? My interpretation will be Option 1 but I wonder if there is a correct answer to interpret this sentence?
