Welcome back. How was your trip? Did you enjoy it?
I noticed that you wrote "2015.1.3" in the order of "year, month, day" which is used in China. While in the United States, the dates are traditionally written in the "month day, year" order. So it should be 1-3-2015. When in Rome, do as the Romans do. Do you agree? Well, just my two cents.
P.S. Here is the link of the date format by country for your references.
