Examples

# coerce POSIXct/Dates to yearquarter
x <- seq(as.Date("2016-01-01"), as.Date("2016-12-31"), by = "1 quarter")
yearquarter(x)
yearquarter(x, fiscal_start = 6)

# parse characters
yearquarter(c("2018 Q1", "2018 Qtr1", "2018 Quarter 1"))

# seq() and arithmetic
qtr <- yearquarter("2017 Q1")
seq(qtr, length.out = 10, by = 1) # by 1 quarter
qtr + 0:9

# display formats
format(qtr, format = "%y Qtr%q")

make_yearquarter(year = 2021, quarter = 2:3)
make_yearquarter(year = 2020:2021, quarter = 2:3)

# `fiscal_year()` helps to extract fiscal year
y <- yearquarter(as.Date("2020-06-01"), fiscal_start = 6)
fiscal_year(y)
lubridate::year(y) # calendar years
