BUG: DatetimeIndex.is_year_start breaks for business-day frequency where `n` is greater than 1 about pandas HOT 4 OPEN

Hi, is is_year_start supposed to return false for both since they are not on 01/01? or is it supposed to both be True. I guess my question is clarifying what is the exact expected behavior. Is the year start when you have a freq with B the first date that is not Saturday or Sunday?

Changed it to check the last character of the string so it handles if there are numbers in front. Works with the example, but not sure about if there are other cases that would break this. The fix seems almost too simple. What do you mean by parse the offset rather than the freqstr?

Sometimes freqstr may have values like "10YS-JAN". I have changed like this (VISWESWARAN1998@8df36f7)

But I believe @MarcoGorelli is expecting something else.

Thank you. I guess we will have to see how @natmokval tackles this issue
