Excel exporting custom date format.

Hi, everyone.  Right now i have created a table with custom date ( YYYY-MM ), but after exporting it shows not correct information.

What if you use yyyy-MM as format?

Y is “week year” and y is year.  Using Y instead of y might cause unexpected results in the last week of December and the first week of January.

Letter	Date or Time Component	Presentation	Examples
y	Year	Year	1996; 96
Y	Week year	Year	2009; 09
