How to print table data between time limit in Laravel 5.6?

in my laravel application I have following table called schools like this

id   name   project   type   created_at   updated_at
1    gfr    bottle    hard   2018-06-25   2018-06-25
2    kio    book      soft   2018-06-27   2018-06-27
3    nhj    vehicle   hard   2018-06-27   2018-06-27
1    nhy    bottle    hard   2018-06-28   2018-06-28
1    gfr    book      soft   2018-06-28   2018-06-28

Now I need controller function to print name,project, and type between 2018-06-27 and 2018-06-28 and I have following controller function

$datas = Schools::orderBy('id','desc')->get();

then how can I filter time limit here
