Source: R/czech_date.R

Usage

as_czech_date(date, case = "genitive")

Arguments

date

date or date-like object to parse.

case

character, either "nominative", "locative" or "genitive" (default) or any unambiguous abbreviation of these.

Value

Same as input, but with class czech_date and attribute gramm_case.

Details

The grammatical case should be specified as and argument to print() method, but for convenience, you can predefine it in as_czech_date call directly. It is then stored as an attribute, later grabbed by the print method.

Note that as opposed to other date formating functions in R, as_date_czech trims leading zeros.

Grammatical cases

Three grammatical cases are supported:

  • nominative -- native form, i.e. "leden" in Czech

  • locative -- "in ...", i.e. "v lednu" in Czech

  • genitive -- "the 'nth' of ...", i.e. "5. ledna" in Czech

Czech months listed by case are available in .czech_months.

Examples

Sys.time() %>% as_czech_date()
#> [1] "21. ledna 2024"

# in "nominative" grammatical case (note the abbreviation)
Sys.time() %>% as_czech_date("nom")
#> [1] "21. leden 2024"
