Time relationship

Formula

overlap = max(0, min(A end, B end)_UTC − max(A start, B start)_UTC), each window converted to UTC by subtracting its offset

= 2

Note

This is a simplified model: it uses fixed conversions (60 minutes per hour, 24 hours per day, 7 days per week, 365 days per year) and ignores leap years, daylight saving changes, public holidays and irregular month lengths. Check the result against a real calendar before relying on it.
