In- "I saw her in Easter." "In" is incorrect. "In" refers to where an object is. Easter is a holiday and can not have any object "in" it.
At- "I saw her at Easter." "At" is incorrect. "At" is used in reference to a precise place. Easter is a day not a place.
On- "I saw her on Easter." "On" is the correct word. "On" is commonly used for dates. For example, I was born ON May 17th. Easter is a date so "on" can be used here.
I`m sorry to contradict you but the expression at Easter is correct:
We have to use AT with :
(1) clock times (EX) at six o'clock
(2) religious festivals (EX) at Christmas, at Easter [meaning at Christmas time / at Easter time]
(3) mealtimes (EX) at breakfast, at lunch, at dinner, at dinner time
(4) other specific time (EX) at night, at the weekend , at weekends, at half-term
On Easter means exactly on Easter Day.
At is used for specific points of time not only for place or location.
at night The stars shine at night.
at the weekend I don't usually work at the weekend.
at Christmas/Easter I stay with my family at Christmas.
at the same time We finished the test at the same time.
at present He's not home at present. Try later.
All the best.
But ... we, Tdol and I, agree with you, on Easter day. The poll example sentence, however, is different. It reads ___ Easter. (There is no day.) So, at Easter. Right? :-D;-)... I must disagree with Cas and Tdol. (Boy is that ever rare!) I thought about what I would say, and since I would say "I'll see you on Easter day" I picked on. As for using in to mean during, I would rather say during. For example: I'll see you during the Easter holidays.
Well, my wife agrees with you. ;-)But ... we, Tdol and I, agree with you, on Easter day. The poll example sentence, however, is different. It reads ___ Easter. (There is no day.) So, at Easter. Right? :-D;-)
I'll see you on Easter day. :tick:
I'll see you at Easter. :tick: poll question
I think some of the differences in opinion have to do with differences in AE and BE. (Not unusual here.)
Thanks.They're OK for me, but I would use firecrackers.
