Mistakes to avoid with time conversions
- Treating every month as 30 days — the average is ~30.44, and finance often uses exact day counts.
- Calling a year exactly 52 weeks — it's 52 weeks plus 1-2 days, which shifts weekday math.
- Ignoring time zones and DST when converting durations across calendar boundaries.
