Hi, I've been trying to import an ASCII file of actual weather data from 2000, which was a leap year, into PVsyst version 6.08. I've tried using the "Dates read on file" option, but instead of reading 29th February when converting, it skips to March, adds a 13th month at the end of the data, and replaces the corresponding weather data with zeros. Is there a tutorial online for importing leap year data, or has someone dealt with this problem before? Thanks!
