Has it already been 3000 days since Girls' Generation's debut? Yes it has, because they debuted with "Into the New World" back on August 5, 2007!

Yoona celebrated the milestone on her Instagram with some beautiful selcas. Congrats to Girls' Generation for maintaining the number one girl group status for all these years! May they have many more thousands of days to come.
