q. about 180-day rule

[alwinms]

When calculating 180-days for employment with employers other than the one who sponsored, how should I calculate the 180 days?
- Should I include saturdays, sundays and federal holidays?
- Should I start from ND or RD?
- Anything else I should consider?

Thanks in advance
