How to obtain the start time and end time of a day?

code like this is not accurate:

 private Date getStartOfDay(Date date) {
    Calendar calendar =          


        

Answer 1

I had several inconveniences with all the solutions because I needed the type of Instant variable and the Time Zone always interfered changing everything, then combining solutions I saw that this is a good option.

        LocalDate today = LocalDate.now();
        Instant startDate = Instant.parse(today.toString()+"T00:00:00Z");
        Instant endDate = Instant.parse(today.toString()+"T23:59:59Z");

and we have as a result

        startDate = 2020-01-30T00:00:00Z
        endDate = 2020-01-30T23:59:59Z

I hope it helps you
