My brand new battery dies after not starting my car for six days. on 1999 Lexus RX300

I tried starting my car after six days of not starting it and there were no lights or engine turnover. I did a jumpstart and it started right up.I am told that there appears to be a parasitic draw. Any advice woould be appreciated.
Thanks

YOU can do this, go out after dark to see if any lights are on anywhere in or on car. Further testing best left to a mechanic. Not many DIY folks can accurately do a parasitic load test!
