how to disable set of days

[abdulkadhir]

@didinj I want to disable the dates that are on my backend.
my JSON format is:
`

[
"2018-01-06",
"2018-01-07",
"2018-01-13",
"2018-01-14",
"2018-01-20",
"2018-01-21",
"2018-01-27",
"2018-01-28"
]` when I tried to convert the above array to date object it throws a runtime error.
can you send me some sample code for this
thanks in advance
