Hi,
I recently learned that the word 'fall' can mean "to happen on a particular day or at a particular time, but I don't understand its usage very well. e.g.
1."New Year's Day falls/fell on a Monday this year."
I have two questions about the sentence above.
a) Should we use 'falls' or 'fell' in the case above?
b) Could I use be verb instead of 'falls' or 'fell' here, as in
"New Year's Day is/ was on a Monday this year."
If so, should we use 'is' or 'was' here?
2."Labor Day is/falls on May 1st."
Are 'falls' and 'is' interchangeable here?
Thank you very much.
