Days Until... 📅

Pick any future (or past) date and this calculator tells you exactly how far away it is in days, weeks, and approximate months. It calculates the difference between today and your target date using millisecond-precision date math, then converts that number into human-readable units. For recurring events, you can also see what percentage of the year has elapsed — useful context for annual planning.

Days = target_date - today. Weeks = floor(days / 7). Months = approximate (days / 30.44).

Use this for countdowns to anything that benefits from a concrete number: a vacation, a deadline, a baby's due date, a retirement date, a wedding, or just Friday. Putting a number on 'how long until' makes abstract future events feel more real and manageable — or more urgent, depending on the number. Both reactions are productive.
