Covid timing question

[margaritaville momma]

Ok so can someone clarify something for me. Is testing supposed to be done 48 hours before or 2 days?  If I am cruising on a Sunday can I test anytime after midnight on Friday or is it 48 hours before my check in time?

Fully Vaccinated Guests
Vaccinated cruises are available for guests who have received their final dose of an approved COVID-19 vaccine at least 14 days prior to the sailing day and have proof of vaccination.

The CDC requires pre-cruise testing for vaccinated guests to be taken within two days prior to the sailing date. If the sailing is on Saturday, the test may be taken on Thursday and Friday, and as late as Saturday, if you are guaranteed to receive your results in time for check-in.

2 days if vaccinated.  My test is scheduled sat at 920 am for monday departure. So more than 48 hours.
