Orla was married in this century, on her lucky day of the week, and her twin sister Enya’s lucky-number day of the month. Enya told Orla on that big day that she intended her own wedding to be on the same lucky day of the week and lucky-number day of the month. She realised that it could not be in the same year as Orla’s, but Orla added that Enya could not be married in the following year, either. Enya married months later, the actual number of months being the sum of the six digits of Orla’s wedding date.
What was Orla’s wedding date?
