In Guangdong standard turnarounds 2020-2022 were 1-2 days (unpopulated) and 3-4 days (fully populated) outside of holiday periods or special cases (>4 layers; exotic substrates; oddball components; custom through-hole soldering). Faster was available for extra money. I'm sure it's accelerated since then. About 9 calendar days international delivery from China is often achieved these days as noted by others and myself.
