| year-month-weekday-count-between {clock} | R Documentation |
This is a year-month-weekday method for the calendar_count_between()
generic. It counts the number of precision units between start and end
(i.e., the number of years or months).
## S3 method for class 'clock_year_month_weekday' calendar_count_between(start, end, precision, ..., n = 1L)

Remember that year-month-weekday is not comparable when it is "day"
precision or finer, so this method is only defined for "year" and
"month" precision year-month-weekday objects.
"quarter" is equivalent to "month" precision with n set to n * 3L.
An integer representing the number of precision units between
start and end.
