The Bootstrap datepicker is able to set date-range. But it is not available in the initial release/Master Branch. Check the branch as ‘range’ there (or just see at https://github.com/eternicode/bootstrap-datepicker), you can do it simply with startDate and endDate.
Example:
$('#datepicker').datepicker({
startDate: '-2m',
endDate: '+2d'
});
