I essentially work 4.5 days per week, on a 9 days/80 hours schedule.

Plus vacations, plus holidays. I am not taking any more Sick Leave, as it adds to my service credit for my pension, if unused.

I'm at the senior level for vacation accrual, so I accrue 5 weeks of VL per year. Plus 12 holidays.

Four and 1/2 days per week x 52 weeks = 234 work days annually.

234 days minus 12 holidays = 222 work days annually.

222 work days minus 25 vacation days = 197 work days annually.

197 days/365 per year.

I have 4 years and one month left.

So 4 years x 197 days plus 20 work days in the last month. So 808 work days left.
