At what point during the year is it inappropriate, if at all to wish someone a “Happy New Year”?

Parker M.: At what point during the year is it inappropriate, if at all to wish someone a “Happy New Year”?
I was “Happy New Yeared” today at work by a new co-worker. I thought this was very strange since we’re nearing the middle of April. My question is: Is there a certain point in the year when New Years Greetings should cease and expire? Does it matter if the greetings continue? Have any of you been given a Holiday greeting after the occassion has passed? What’s your perspective on this topic?
The new co-worker was not joking or being sarcastic. She was very sincere. She introduced herself to all staff members and management with the same greeting. She seemed very sane.

Generally by the beginning of Feb. it would seem a bit late. March would be odd. April, well that is just plain stupid. You could counter (bearing in mind this could continue) in May “so ‘ja have a nice Easter?”

Was this person lucid at the time?

No clue, maybe it was meant as a form of sarcasm. Usually after mid-January, it’s over. It’s a bit like saying Merry Christmas in July. But to each their own.

I would say beginning of Feb.

Very odd!
Maybe in her religion or culture it might be new year?
Still odd though.
I think once January is over so should the ‘Happy New Year’ greetings

Answer by Classy Granny
I’d say once we make it through January we can quit saying Happy New Year.
