In this image we see 45 as the birthdate of Hafsah bint Umar Ibn Al-Khattab, I think it should be written 645 instead but the 6 isn't there for some reason. Unless it's supposed to be the Hijri year but in that case it isn't clear and from 622 to 665 it would be 43 years and not 45. So I think it's the problem I first mentioned.
BarakAllahu fikum.
