What 100 Business Days Actually Means
100 work days — about 20.0 work weeks (140 calendar days)
100 business days is a long-range working deadline — about 20.0 work weeks, translating to roughly 140 calendar days once weekends are added back in. Timeframes this long are found in enterprise procurement, federal permitting, and extended commercial underwriting windows.
Over 100 business days you'll typically see 20–21 weekends and at least one public holiday in most countries. The more important the deadline, the more worth it is to confirm which holiday calendar the count uses — different regulators and different jurisdictions disagree.
Common Uses for a 100-Business-Day Window
- Federal permitting and regulatory review
- Enterprise vendor procurement cycles
- Commercial real estate closing timelines
- Extended professional certification review
- Long-duration public-comment periods
