Has probably been discussed before but I couldn't find it.

6Y14 = 2016/11/14


1. 1st digit = Year (5 = 2015, 6 = 2016, 7 = 2017 and so on).
2. 2nd digit = Month (1 =Jan, 2 =Feb, 3 =Mar, 4 =Apr, 5 =May, 6 =Jun, 7 =Jul, 8 =Aug, 9 =Sept, 10 =X, 11 =Y, 12 = Z).
3. The 3rd and the fourth together = day(01, 02, 03, 04….29, 30, 31).
