Term times
The University has set dates for when the semester starts and ends and for the four periods dividing each semester. The dates are found in a Swedish document, but regardless of your level of Swedish, you can work out the dates for the autumn semester ("hösttermin") and spring semester ("vårtermin"). The date format used is YYYY-MM-DD (year, month, day).
Look at section "3.1 Läsårets förläggning (terminstider)" for semester start and end, and the appendix for the division of each semester:
