1376：Calendar

Calendars in widespread use today include the Gregorian calendar, which is the de facto international standard, and is used almost everywhere in the world for civil purposes. The Gregorian reform modified the Julian calendar's scheme of leap years as follows:
Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100; the centurial years that are exactly divisible by 400 are still leap years. For example, the year 1900 is not a leap year; the year 2000 is a leap year.

In the first line, the is a integer T (1≤T≤100), which means there T cases of this problem.
In every case, the input has two format:
1):  yyyy1:mm1:dd1 yyyy2:mm2:dd2
2):  yyyy1:mm1:dd1 day
If the format is the 1) type, your task is to calculate how many days are between yyyy1:mm1:dd1 and yyyy2:mm2:dd2.
Others, your task is output the date after the date yyyy1:mm1:dd1, and the days between them is day. The format of the answer is yyyy:mm:dd.
1000≤yyyy≤9999 and yyyy:mm:dd is a legal date.
0≤day, we can ensure the answer of the second type is satisfied with 1000≤yyyy≤9999.

For every case, display the answer of this question per line.
