# daterange

daterange is a simple node/browser library to work with date ranges.

Compare whether date ranges are equal, overlap, or contain each other.

Subtract and add date ranges.

daterange is simple and fast.

Install via

  • npm install daterange
  • bower install daterange

The bower install is just the main src file, bower.json and readme

Basic Examples

Node Example
var daterange = require('daterange');
var range1 = daterange.create( new Date(2000, 0, 1), new Date(2000, 0, 3) );
Browser Example
<script src="/bower_components/daterange/src/daterange.js"></script>
<script>
  var range1 = daterange.create( new Date(2000, 0, 1), new Date(2000, 0, 3) );
</script> 

Examples cont.

Add 2 ranges:
var range1 = daterange.create( new Date(2000, 0, 1), new Date(2000, 0, 3) );
var range2 = daterange.create( new Date(2000, 0, 2), new Date(2000, 0, 4) );
var result = range1.add( range2 );
 
result[0].start.getTime() === range1.start.getTime(); // true
result[0].end.getTime() === range2.end.getTime(); // true
Sum 2 continuous ranges:
var range1 = daterange.create( new Date(2000, 0, 1), new Date(2000, 0, 3) );
var range2 = daterange.create( new Date(2000, 0, 2), new Date(2000, 0, 4) );
var result = daterange.sum( [range1, range2] );
 
result[0].start.getTime() === range1.start.getTime(); // true
result[0].end.getTime() === range2.end.getTime(); // true
Sum 3 ranges with break inbetween:
var range1 = daterange.create( new Date(2000, 0, 1), new Date(2000, 0, 3) );
var range2 = daterange.create( new Date(2000, 0, 2), new Date(2000, 0, 5) );
var range3 = daterange.create( new Date(2000, 0, 7), new Date(2000, 0, 8) );
var result = daterange.sum( [range1, range2, range3] );
 
result.length; // 2
result[0].start.getTime() === range1.start.getTime(); // true
result[0].end.getTime() === range2.end.getTime(); // true
result[1].start.getTime() === range3.start.getTime(); // true
result[1].end.getTime() === range3.end.getTime(); // true
Inverse ( Identify gaps in summed ranges ):
var range1 = daterange.create( new Date(2000, 0, 2), new Date(2000, 0, 5) );
var range2 = daterange.create( new Date(2000, 0, 7), new Date(2000, 0, 8) );
var result = daterange.inverse( [range1, range2] );
 
result[0].start.getTime() === range1.end.getTime(); // true
result[0].end.getTime() === range2.start.getTime(); // true
// Illustration:
//
// range1      end1  start2  end2
// v             v     v      v
// #-------------#     #------#
//
//               #-----#
//               ^     ^
//          start  GAP  end

daterange Methods:

range = daterange.create(Date, Date);
ranges = daterange.sum([range,range,...]);
bool = daterange.equals(range1, range2);
bool = daterange.contains(outer, inner);
bool = daterange.overlaps(range1, range2);
ranges = daterange.subtract(range1, diffRange);

daterange Instance Methods, from daterange.create:

bool = range.equals(range);
bool = range.contains(range);
bool = range.overlaps(range);
ranges = range.subtract(range);
ranges = range.add(range);
