leap year

Hi all! I was wandering if there is a way to "avoid" the 29th February occurring on leap years. This is because I am carrying out a 10 years simulation with a daily time-series, meaning that I assign a different value (heat extraction by a BHE) to every day of the year. However if I have one more day every 4 years the time-serie is shifted by one day every 4 years... and even if slightly the results do not perfectly match the calendar. Any solution suggested?

Use 365.25/365 = 1.000685 for a day instead of 1? We typically use 365.25/12 for monthly timestepping. Haven't really done daily timestepping before, but I'd give that a try.
