How to Convert Modified Julian Dates to R's POSIXct Format for Astronomy and Time-Related Calculations
Understanding Modified Julian Dates and R’s POSIXct Format In astronomy, the Julian Date is a continuous count of days since January 1, 4713 BCE (Unix Epoch). This date system was originally proposed by Joseph-Jérôme Léonard de Saulty in 1786. The modified Julian Date takes into account leap years and other adjustments to ensure that it remains consistent across time zones. R uses the POSIXct format to represent dates and times. This format is a combination of the system’s current date and time, plus an offset in seconds from Coordinated Universal Time (UTC).
