Usage

## S3 method for class 'clock_year_quarter_day'
calendar_start(x, precision)

## S3 method for class 'clock_year_quarter_day'
calendar_end(x, precision)

Arguments

precision

⁠[character(1)]⁠

• "minute"

• "second"

• "millisecond"

• "microsecond"

x at the same precision, but with some components altered to be at the boundary value.

Examples

x <- year_quarter_day(2019:2020, 2:3, 5, 6, 7, 8, start = clock_months$march)
x

# Compute the last moment of the fiscal quarter
calendar_end(x, "quarter")

# Compare that to just setting the day to `"last"`,
# which doesn't affect the other components
set_day(x, "last")

# Compute the start of the fiscal year
calendar_start(x, "year")

as_date(calendar_start(x, "year"))
