Capturing Application.Match error using loops

[IRN_HU]

I want to locate the position of two dates inside a list of sequential dates.

The list is arranged earliest date to latest date.

The first date is the start_date, if the start_date is not contained in the list, it should increase by one until a match occurs.

The second date is the end_date, if the end_date is not contained in the list, it should decrease by one until a match occurs.

I currently use Application.Match to look for each date, and unsuccessfully try to fit a loop to capture any error, and increase (decrease) the start (end) date.
