What Is 120 Calendar Days From Today?
120 calendar days from today is —. "Calendar days" means every day of the week — weekends and public holidays are all counted. This distinction matters when contracts, statutes, or deadlines specifically say "calendar days" instead of "business days".
One hundred twenty calendar days is four months of strict clock time — matters for USCIS processing windows and some contract extensions.
Calendar Days vs. Business Days
This is the difference that trips people up most. Calendar days count every single day — Monday through Sunday, plus holidays. Business days only count Monday through Friday, skipping weekends (and sometimes federal holidays, depending on context).
Specific uses: One hundred twenty calendar days is the standard USCIS H-1B 'premium processing' window (though this is occasionally suspended), the maximum pre-trial detention window in many federal criminal cases before habeas review, and the typical 'extended warranty' window for many electronic products sold in US retail.
When To Use Calendar Days
Calendar-day counts are the default in most US legal and commercial contexts. You'll see them explicitly required in:
- Tax filings and IRS extension windows
- Real estate closing deadlines (including 1031 exchanges)
- Federal and state statutes of limitations
- Product return and warranty policies
- Insurance claim filing windows
