ee.DateRange.intersects

  • The intersects() method determines if two DateRange objects share any common points in time.

  • It returns true if there's an overlap between the date ranges, otherwise it returns false.

  • The method takes one argument, other, which is the DateRange to compare against the original.

  • This function is useful for filtering or analyzing temporal data based on overlapping time periods.

 Returns true if the given DateRange has at least one point in common with this DateRange.

// A series of ee.DateRange objects.
var dateRange1 = ee.DateRange('2017-06-24', '2017-07-24');
var dateRange2 = ee.DateRange('2017-06-30', '2018-07-10');
var dateRange3 = ee.DateRange('1970-06-24', '1971-07-24');
var dateRange4 = ee.DateRange('2017-06-25', '2017-07-25');

// Determine if an ee.DateRange intersects another.
print('Does dateRange1 contain dateRange2?', dateRange1.intersects(dateRange2));
print('Does dateRange1 contain dateRange3?', dateRange1.intersects(dateRange3));
print('Does dateRange1 contain dateRange4?', dateRange1.intersects(dateRange4));
