For I have bunch of categories which is calendar days "sun 19 feb" , "tue 20 feb" etc.
Each category has they own products. So when customer want to buy products from cat. "mon 19 feb" he can do that not after this date.

I can actually understand the logic. But don't know how to write down the script.

Example:
$categorydate1 - 02/19/2017
$date - 04/03/2017 (actual date)

if ($date<$categorydate1) then
div.ecwid-productBrowser-categoryPath {
display:none;
}
