java - How do I get the date of 31 days ago? -

how can x should 31 days before current_date?

x(date)___________________________current_date                        31

just subtract 31 days. example:

localdate current = new localdate(2015, 6, 19); localdate x = current.minusdays(31); // 2015-05-19

to get current date, use:

localdate current = new localdate(); // default time zone

localdate current = new localdate(zone); // specific zone

or may want create own "clock" representation able give current instant, in case you'd use:

localdate current = clock.getcurrentinstant().todatetime(zone).tolocaldate();

(that lets use dependency injection write simpler unit tests fake clock.)
