下面的查询给出了提供的日期范围（开始和结束日期）与table_name中的任何日期（开始和终止日期）重叠的ID

select id from table_name where (START_DT_TM >= 'END_DATE_TIME'  OR   
(END_DT_TM BETWEEN 'START_DATE_TIME' AND 'END_DATE_TIME'))

简单的解决方案：

compare the two dates: 
    A = the one with smaller start date, B = the one with bigger start date
if(A.end < B.start)
    return false
return true

使用momentjs的简短回答：

function isOverlapping(startDate1, endDate1, startDate2, endDate2){ 
    return moment(startDate1).isSameOrBefore(endDate2) && 
    moment(startDate2).isSameOrBefore(endDate1);
}

答案基于上述答案，但缩短了。

我找到了另一个非常简单的方法。如果daterange1的开始和结束日期在daterange2的开始日期之前，或者daterange3的开始和终止日期在daterange2的结束日期之后，这意味着它们彼此不相交。

public boolean doesIntersect(DateRangeModel daterange1, DateRangeModel  daterange2) {
    return !(
            (daterange1.getStartDate().isBefore(daterange2.getStartDate())
                    && daterange1.getEndDate().isBefore(daterange2.getStartDate())) ||
                    (daterange1.getStartDate().isAfter(daterange2.getStartDate())
                            && daterange1.getEndDate().isAfter(daterange2.getEndDate())));
}

对于ruby，我也发现了这一点：

class Interval < ActiveRecord::Base

  validates_presence_of :start_date, :end_date

  # Check if a given interval overlaps this interval    
  def overlaps?(other)
    (start_date - other.end_date) * (other.start_date - end_date) >= 0
  end

  # Return a scope for all interval overlapping the given interval, including the given interval itself
  named_scope :overlapping, lambda { |interval| {
    :conditions => ["id <> ? AND (DATEDIFF(start_date, ?) * DATEDIFF(?, end_date)) >= 0", interval.id, interval.end_date, interval.start_date]
  }}

end

在这里找到它，解释很好->http://makandracards.com/makandra/984-test-if-two-date-ranges-overlap-in-ruby-or-rails

这是我使用moment.js的javascript解决方案：

// Current row dates
var dateStart = moment("2014-08-01", "YYYY-MM-DD");
var dateEnd = moment("2014-08-30", "YYYY-MM-DD");

// Check with dates above
var rangeUsedStart = moment("2014-08-02", "YYYY-MM-DD");
var rangeUsedEnd = moment("2014-08-015", "YYYY-MM-DD");

// Range covers other ?
if((dateStart <= rangeUsedStart) && (rangeUsedEnd <= dateEnd)) {
    return false;
}
// Range intersects with other start ?
if((dateStart <= rangeUsedStart) && (rangeUsedStart <= dateEnd)) {
    return false;
}
// Range intersects with other end ?
if((dateStart <= rangeUsedEnd) && (rangeUsedEnd <= dateEnd)) {
    return false;
}

// All good
return true;
