The economy updates are very early Monday morning (local time), so those for Australia and East Asia happen Sunday afternoon USA time, and those in Europe on Sunday evening USA time. The USA update is at 3 AM CST.
The transfer deadlines are set for 72 hours plus a random amount between 0 and 24 houirs, so some of the earliest players will have deadlines on Wednesday afternoon, USA time, and the very latest will be very early on Friday morning.
Much fewer players are being released this week. For example, in the USA, instead of 57 players, it is 3 players.
