I am asking about whether pleasant time should have a before it - a pleasant time. In my opinion, I don't think so since it is uncountable noun, do it? But I was confused after I read it in an article on the internet.
I wish I had better English, but I work hard to improve it. I'm studying for IGCSE, so I'm only interested in BrE.
Without context it's hard to tell. However, if you say "I had a pleasant time in Italy" then yes, you need the indefinite article. Here, "time" is used to mean "a period of time" or (in this case) "a stay" or "a holiday".
