Description

Convert a julian date into a standard calendar date format

Usage

1

Arguments

x

julian date; that is, the number of days since day 0 (default is 1970-01-01)

Details

In R, the julian function converts a date-time object into a Julian date: the number of day since day 0 (default is 1970-01-01). However, there is no function, without loading another package, that converts a Julian date back into a date object. The julian2date function does this conversion.

Value

Return standard calendar date format.
