Ever been in a meeting and someone says "how many business days until the deadline?" and everyone starts counting on their fingers?
I built a free day calculator that handles this in 2 clicks.
What It Does
4 tools in one page, all free:
- 📅 Business Days Calculator — Count Monday-Friday only, perfect for project timelines and shipping estimates
- 📆 Date Difference — Exactly how many calendar days between any two dates
- ⏰ Countdown Timer — Live ticking countdown to any date (or "days since" calculator)
- 🇺🇸 US Holidays 2026 — All federal holidays at a glance
Quick Example
Need to know how many working days until June 30?
Business Days Calculator → June 15 to June 30 → 11 business days
That's it. No calendar math, no finger counting.
Why I Built It
I run projects with deadlines and I was always Googling "business days between two dates" or "how many days until X". Every site was cluttered with ads or missing the countdown feature. So I built my own.
100% free. No signup. Not even a cookie banner. All math happens in your browser.
