Per the docs, justify_days is to "Adjust interval so 30-day time periods are represented as months" so 360 days = 12 months = 1 year so 365 days is 1-year 5-days.
There are all sorts of oddities and special assumptions regarding date/time calculations made even more complicated by the need to support special use-cases such as 30/360 financial coupon factor calculations (every month is 30-days and years have 360 days).
Cheers,
Steve

Description:
Hi,
I am going through PostgreSQL, for the first day. And it was great till
now.
One quick question/doubt regarding the function "justify_days(interval)"
select justify_days(interval '365 days');
this statement returns 1 year 5 days, whereas I feel it should be just 1
year.
Please correct me if I am wrong.. Thanks for all your time.
