$ isFirstWeek(date : Date) -> Boolean
// true if it is in first week.

// true if it is in last week.
$ monthRange(s : Number, e : Number, f : Number -> b) -> [b]
// Returns a range of days from 's' start and 'e' end.
// For each day apply function 'f'.
//
// Note: 's' and 'e' are not checked if they are actually in the month.
// Use `rangeInMonth` to validate those values.
$ rangeInMonth(d : Date, s : Number, e : Number, f : Number -> b) -> [b]
// Returns a range of days from 's' start and 'e' end.
// Use date 'd' to check if 'e' don't pass the last day of the month,
// if it does, return the last day.
