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".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
