Examples

x <- year_quarter_day(2019, 1:4)
x <- c(x, set_year(x, 2020))

# Group by 3 quarters
# Note that this is a grouping of 3 quarters of the current year
# (i.e. the count resets at the beginning of the next year)
calendar_group(x, "quarter", n = 3)

# Group by 5 days of the current quarter
y <- year_quarter_day(2019, 1, 1:90)
