ERROR - month must be in 1..12

[allisonwelch]

I am plotting a back trajectory frequency plot. The initial date is 220621 (June 21, 2022) and the end date is 220628 (June 28, 2022), with the trajectory calculation run every 6 hours. All the scripts seem to run fine and the plot is generated, except for one error message which says: "ERROR - month must be in 1..12: using 1970-01-01 00:00:00+00:00" This error is given a total of 4 times when I execute the python display. I don't get the same error when executing the fortran display, but the plot has the same issue of displaying 1970-01-01 00:00:00+00:00. Can anyone help me with locating where this date format problem is and how to fix it?

Thanks,

The error message is printed by the make_datetime() function in python/hysplitdata/hysplitdata/util.py. The top-level directory here called 'python' should be found where your HYSPLIT v5.2 is installed.
