Examples
# There is a big difference between adding this rule to a `yearly()`
# or `monthly()` frequency, and a `daily()` frequency.
# Limit from every day to every day in February
on_feb_daily <- daily() %>% recur_on_month_of_year("Feb")
# Limit from 1 day per month to 1 day in February
on_feb_monthly <- monthly() %>% recur_on_month_of_year("Feb")
start <- "1999-01-01"
end <- "2001-01-01"
alma_search(start, end, on_feb_daily)
