Mistake on accommodation details leave date

[yasir152]

Hi

I have applied for a visitor visa to the UK for my mother-in-law and am her sponsor. After submitting the application I have noticed a slight error in the accommodation details section. The arrival date is 20th may and the leave date entered is 30th may whereas I should have put 30th june,
Will this affect the application if I have stated that it is to visit family as it is only 10 days?
I haven't mentioned anything about visiting dates in other supporting documents.

Regards

Yasir
