search for: 140th

...when I apply the Julian function: > julian(months(ymd),days(ymd),years(ymd),origin=c(month = 1, day = 1, year = as.numeric(years(ymd[1])))) I get the following result: [1] 137 137 137 138 138 138 138 139 139 139 However, when I check on the calendar, the dates I have correspond to the 139th, 140th and 141st days of the year (there is a two days shift because it is a leap year, for other years I have a one day shift). I tried the default origin when I use the dates function but I get the same results. Did anyone have this problem before ? I would appreciate some help, Thank you very much...
