a day/the day/one day after she did it

[Mack&Mack]

Hello,

Can anyone tell me which sentence is correct or more common than the others, please?

Ms. Kim called me to say ‘thank you’ the day after she borrowed the money from me.

Ms. Kim called me to say ‘thank you’ a day after she borrowed the money from me.

Ms. Kim called me to say ‘thank you’ one day after she borrowed the money from me.

Thank you in advance.

Hello Mack. They're all grammatically correct of course, but I think the first sounds the most idiomatic.
(In the second you're emphasizing how long it was before she called, in the third the precise number of days it was.)

The last sentence is unusual.
The other two are both fine but perhaps subtley different. If you say "the day after" then I think there is a slight implication that the listener knows what day Ms. Kim borrowed the money but it's so slight as to be hardly worth mentioning. In any case, I think it's more common to say "the day after".
