How to get the first date and last date of current quarter in java.util.Date

Question

I need to get the first date of the current quarter as a java.util.Date object and the last date of the current quarter as a java.util.Date

Answer 1

you can use java 8 LocaDate to get current quarter first and last day

The code below gives you.

public static LocalDate getCurrentQuarterStartDay(LocalDate date) {
        return date.with(IsoFields.DAY_OF_QUARTER, 1L);
    }

public static LocalDate getCurrentQuarterEndDate(LocalDate date) {
        return date.with(IsoFields.DAY_OF_QUARTER, 92L);
    }

Here in second method the 92 has partially lenient

The day-of-quarter has values from 1 to 90 in Q1 of a standard year, from 1 to 91in Q1 of a leap year, from 1 to 91 in Q2 and from 1 to 92 in Q3 and Q4
