a picture 14 x4 could also be put in instead of the saying

, BUT
in my rush to get the pictures taken I set the template wrong, I made dec with only 30 days,
goes to show its flexible, see the new posed photos

I did miss 2 days, but you still have to know what months have 30 days, also I need to not trust what you see on the net
should have verified it before the work, but its fixed now and I used a picture instead of a saying
