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).
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.
