Hi, I plan to renew my passport (first before booking my hotels and flight) but wondering on the "if did not receive any email after 3 days, can straight go to your selected branch to collect". What is that 3 days means?

Here's an example:
Monday (today) - do ntg
Tuesday (2/8/22) - submit all relevant documents to the immigration website (assuming all green light)
Wed
Thurs
Fri (5/8/22) - is this day considered "after 3 days" or I need to wait until Saturday (6/8/22) only is considered "after 3 days"?

Just need the clarification on that "after 3 days". Thanks!

Thanks for the confirmation. Anyways, which one would you personally recommend to go as the Q may be shorter or the process is faster? (Klang Valley)
