Fans of BBC soap EastEnders spotted a St Patrick's Day gaffe during an episode that focused on a harrowing bullying storyline.
In Friday's instalment of the programme, viewers saw the bullying that Bex Fowler (Jasmine Armfield) has been suffering at school step up a gear when she was attacked in the toilets.
But when a teacher finally discovered Bex hiding from classes and brought the three bullies - Alexandra D'Costa (Sydney Craven), Madison Drake (Seraphina Beh) and Louise Mitchell (Tilly Keeper) - in for questioning, fans spotted a clanger of a mistake.
As they waited to speak to the head teacher, Madison sent reluctant bully Louise a message that read: "Remember, say nothing," which was dated Friday February 17 rather than March.
To emphasise the error, other characters were seen celebrating St Patrick's Day in Albert Square pub The Queen Vic during the episode.
@RebeccaWbu_94 tweeted: "Everyone is saying about how good the storyline is and there's me being mrs marple about Louise's phone!"
@JanJan_81 tweeted: "Wrong month on the phone message @bbceastenders #whoops #filminginadvanceproblems #eastenders"
@mazzymoo5 tweeted: "So it's February in Eastenders land??? According to Louise's phone it is..."
EastEnders films scenes a number of weeks in advance of them airing on BBC1.
The soap continues on Monday at 8pm.
