Emmerdale fans believed they spotted a plothole in today's epsiode.
Moira Dingle's downward spiral continued as she was forced to face up to her actions.
On Friday, viewers saw her drowning her sorrows after Cain refused to rekindle their marriage.
Upon her son Matty's return, she threw a wine bottle and glass at him in temper.
Today, Matty announced that he'd had enough of her antics and had decided to move out.
This was confirmed by Matty informing his mum that it was her and his dad's wedding anniversary - which she had forgotten.
However, viewers pointed out one fact they couldn't get their head over.
Matty said today would be his parents thirtieth wedding anniversary.
This prompted viewers to take to Twitter in an attempt to work out the maths.
If Moira is the same age as the actress Natalie J Robb who plays her, she would be just 45 years old - too young to be legally wed.
One took to Twitter saying: "Moira was married at like 2 years old. How’s she having a 30 year anniversary? What is her secret? Can I have some of that youth serum? "
Ally said: "30 years ago moira was married? Wait, how old is she?"
Mandy wrote: "Apparently she's meant to be 48 yeh right looks it not."
