A woman gave birth to Twins; The first baby came out 11.55 pm 31st December 2012 and the other came out by 00.05 on 1st January 2013, I over heard somebody saying dey were not born the same year.
Pls are they still Twins? And is the Taiye the senior or Kehinde?
Would they celebrate their birthday differently? Ur Opinion pls!!!!!

Nothing puzzling about this. Yes, they're still twins.
Whoever came out first is the older of the two.

Technically, the dates are different so I'd say yes. However, people who share close birthdays, even several days apart sometimes celebrate their birthdays on the same day, their choice.
