The PlayStation 2 (PS2) was released in stages between 2000 and 2001:

• Japan: March 4, 2000
• North America: October 26, 2000
• Europe: November 2000 (roughly November 24–23 depending on region)
• Australia: November 30, 2000

If you need a specific region date or launch window for a particular edition (original vs Slimline), I can pull exact dates for that variant.
