About TallyDays

TallyDays is a set of free date tools for people in the United States: countdowns to any date or holiday, the number of days between two dates, dates a number of days or business days from today, week numbers, and age by birth year.

Every answer is calculated, not looked up

Each page computes its answer when you load it, using today's date in Eastern Time (America/New_York). The page shows the date it counted from and the rules it used, so you can check the result against your own count.

Built around U.S. business days

Many calculators treat every weekday as a business day. Ours skip weekends and the 11 annual U.S. federal holidays, using the day federal offices actually close when a holiday falls on a weekend. Every holiday a result skips is listed by name, so you can adjust for your own employer or state schedule.

Who runs this site

TallyDays is published by TallyDays. It is not affiliated with any government agency. Holiday rules come from official sources, listed on our How we calculate page.

Found a mistake?

Date math can look right and still be off by one day. If an answer looks wrong, please tell us which page and date you used, and we will check it.
