Include the same boilerplate from the top of Velocitip: Find the first Y-day of next month:
#set( $defaultTimeZone = $date.getTimeZone().getTimeZone("America/New_York") )
#set( $defaultLocale = $date.getLocale() )
#set( $calNow = $date.getCalendar() )
#set( $ret = $calNow.setTimeZone($defaultTimeZone) )
#set( $calConst = $field.in($calNow) )
#set( $ISO8601DateOnly = "yyyy-MM-dd" )
#set( $ISO8601DateTime = "yyyy-MM-dd'T'HH:mm:ss" )
#set( $ISO8601DateTimeWithSpace = "yyyy-MM-dd HH:mm:ss" )
#set( $ISO8601DateTimeWithMillisUTC = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'" )
#set( $ISO8601DateTimeWithMillisTZ = "yyyy-MM-dd'T'HH:mm:ss.SSSZ" )
Then a slight tweak to that code to find the Xth Y-day of this month:
#set( $nth = 4 )
#set( $day = "WEDNESDAY" )
#* NO NEED TO TOUCH BELOW THIS LINE! *#
#set( $dayConst = $calConst.get($day) )
#if( $dayConst < 7 )
#set( $nextDayConst = $math.add($dayConst,1) )
#else
#set( $nextDayConst = 1 )
#end
#set( $thisMonth = $date.getCalendar() )
#set( $ret = $thisMonth.setTimeZone($defaultTimeZone) )
#set( $ret = $thisMonth.set($calConst.DAY_OF_MONTH, 1) )
#set( $ret = $thisMonth.setFirstDayOfWeek($nextDayConst) ) ## the day *after* Y-day
#set( $ret = $thisMonth.set($calConst.DAY_OF_WEEK, $dayConst) ) ## Y-day itself
#set( $ret = $thisMonth.add($calConst.WEEK_OF_MONTH, $math.sub($nth,1) ) )
And output that day in your chosen format:
The ${nth}th/nd ${display.capitalize($day.toLowerCase())}
of ${date.format("MMMM yyyy", $thisMonth, $defaultLocale, $defaultTimeZone)}
is ${date.format("MM/dd/yyyy", $thisMonth, $defaultLocale, $defaultTimeZone)}
P.S. In the future, better to avoid the term “select” as that’s kind of vague and sounds like you’re talking about a filter. “Output in an email” is more appropriate.
