date, gregorian-calendar, java
Solution
set the hours, minutes and seconds in your calendar object to zero.
gc.set(GregorianCalendar.HOUR_OF_DAY, 0);
gc.set(GregorianCalendar.MINUTE, 0);
gc.set(GregorianCalendar.SECOND, 0);
gc.set(GregorianCalendar.MILLISECOND,0);
Remember to do this AFTER you have called `gc.add`.
Problem
i am trying to mark date if the data created in the past 3 days. I want to take the last 3 days , from the beginning (00:00). i have this code : ``` int days = 3 GregorianCalendar gc=new GregorianCalendar(); gc.add(GregorianCalendar.DAY_OF_MONTH, -days); if (timeCreated.before(gc.getTime())) { return true; } return false; ``` if the current time is 16:00 clock i get the past 3 days , from 16:00 clock to now. I want to get from 00:00 3 days ago till now.
