how can I convert day of year to date in javascript?

Question

I want to take a day of the year and convert to an actual date using the Date object. Example: day 257 of 1929, how can I go about doing this?

Answer 1

If I understand your question correctly, you can do that from the Date constructor like this

new Date(year, month, day, hours, minutes, seconds, milliseconds)

All arguments as integers
