Add a year to a date (and deal with leap year)

Using "Mongodb" shell, I have to compute the date of the day + one year. I can add 365 days do the current date, but I'll be wrong with leap year. Example: 

print(new Date(new Date().getTime() + (1000 * 3600 * 24 * 365)));

We are "2015-06-22". This "date + 365 = 2016-06-21" :) I have not found any date function on Mongodb. How do you deal with leap year?

Supposing you just want it to be the same date for the next year you can use 

var a = Date()
a.setFullYear(a.getFullYear() + 1)

As Sylvain Leroux points out you will have to handle the edge case of the 29th of February by default it will change to the first of March when you add a year. This will not happen if you add a year to march 1st of the year before a leap year.
