Hi shaan,
if your using bootstrap date picker widget u have an option like
min date and max date which meets the date criteria
current date : 11/12/2018 is bold
the same you can do it for future date in red
using css
td.active.day {
}
example code
td.day{
color:red
}
hope this helps !!
You could add some conditional formatting. If date meets criteria, show/hide object with styling.
