使用Javascript或MomentJS获取上个月的最后一天

Question

I have fetched first and last day of the month in MomentJS like this:

 var startDate = ConvertToNewDateFormat(new Date(date.getFullYear(), date.getMonth(), 0));
        var endDate = ConvertToNewDateFormat(new Date(date.getFullYear(), date.getMonth() + 1, 1));

This returns lets say:

2016-05-01 -> start

2016-05-31 -> end

What I need is day before 05-01 and day after 31.05 (in general for every month like that), ie last day of previous month and first day of next month... How can I do this ??

Answer 1

  start=moment().startOf('month');
  end=moment().endOf('month');
  lastDayOfPrevMonth =moment(start).subtract(1,'day')
