this is wrong because first interval is 1008 hour and the second is 1000
hours

In the first case you have a month with 31 days and in the second you
have a month with 30 days

try this

select
age(current_timestamp , current_timestamp - '1008 hours'::interval)
> interval '1000 hours'

so 1000 > 1008=20
