Custom Fields - Creating a rank column based on earliest date when at specific point

[CYY]

Good day,

I work in shipping and logistics. I’m looking to create a column showing a rank (1,2,3...) based on the sailing date of a ship at a specific port.

FYI All ships start with the same port and there’s a date column for each port, so the easiest way might be to add a filter (?)

Thank you in advance for your insight!
