Sweden admission deadlines
Are Swedish programs deadlines have a typical norm and are on fixed dates such as U.S. (Nov, Jan, Feb) or they're based on the advertising dates and are somehow unique?


The most common way to announce PhD positions is on a case-by-case basis with unique deadlines for each position. There are no fixed dates that universities have to adhere to. You will see an increase in the number of available positions during the first quarter of each year since big funding bodies like the Swedish Research Council decide on grants in the fall.
