Hi!
Thanks for your answer Sean I got it solved using clj-time
Also I found the problem with my macro attempt
user> (defmacro is
[s instant]
`(= (.get ~instant Calendar/DAY_OF_WEEK)
(. Calendar ~s)))
#'current-day.core/is
user> (is FRIDAY (Calendar/getInstance))
false
user> (is WEDNESDAY (Calendar/getInstance))
true
I was quoting the symbol !!
