The Hoops are already back for pre-season ahead of the Champions League qualifiers, which begin in July.
In the majority of top-flight leagues, the off-season tends to be longer, with a summer break in the region of eight weeks, while in Scottish football, European qualifiers and League Cup fixtures mean that teams have competitive action in July, which has a knock-on effect on the amount of time players have off.
In Celtic's case, they are already back in pre-season ahead of their Champions League qualifiers, with the first qualifying round getting underway on 9-10 July (Herald Scotland), and some clubs have already returned to pre-season training only a week after a round of Euro 2020 qualifiers (BBC Sport).
While Brown, who is gearing up for his 13th pre-season at Parkhead, says he is now accustomed to two or three weeks' holiday, he admits that new arrivals are shocked at first and find it more difficult, but on the plus side they don't lose as much match sharpness.
"It's always harder for the new ones when they come in for their first season," Brown is quoted by the Daily Record as saying. "They come in and are like: ‘Two or three weeks holiday? We should be getting eight.’
"It’s football now. Scottish football as it seems to be because our seeding level isn’t as good as what it used to be. You always lose your sharpness after a week or two, but you can pick that up in a couple of weeks, plus the international break lads will have lost pretty much nothing. It’s short and sharp for them, but they won’t have lost too much."
The draw for the Champions League qualifying rounds will take place in Nyon, Switzerland, today at 1:30pm BST.
