Earlier, when I had dates in a column like:
Monday, 21 April, 2014 Tuesday, 22 April, 2014
and I extended the last cell to lower cells I could expect them to be filled with following days:
Wednesday, 23 April, 2014 Thursday, 24 April, 2014
but now I get:
Tuesday, 22 April, 2015 Tuesday, 22 April, 2016
Why is that? All cells in column are in date format.
