Date Difference Formula

Date₁, Date₂ = Any two calendar dates
ms = Difference in milliseconds
86,400,000 = Milliseconds per day

ℹ️ Weeks = days ÷ 7 | Months ≈ days ÷ 30.44 | Years ≈ days ÷ 365.25

Frequently Asked Questions

💡

Pro Tips

1

Business days vs calendar days matter for deadlines. A 30-day contract deadline is 30 calendar days, but a "30 business day" deadline is closer to 6 weeks.

2

Leap years (every 4 years, except century years not divisible by 400) add 1 day. Long-term date calculations that span February should account for this.

3

For countdown timers to important dates, include time zones — "Friday midnight" in New York is 3 hours different from California.

4

Age in years alone hides important milestones. "30 years, 6 months" is much more precise than "30 years old" for medical or legal calculations that need exact age.
