Question 1

Is today included when a countdown counts down to an event?

Accepted Answer

No — the headline "days until" figure measures the span from today's midnight to the target date's midnight, so the current day isn't double-counted as part of the wait. If your event is today, the counter reads 0 and the live clock ticks down the remaining hours, minutes, and seconds until midnight instead. That's a different question from "how many days does this span cover," which would count both endpoints — most people expect the exclusive version when they ask how long until something happens.

Question 2

How does the live countdown clock stay accurate while I leave the page open?

Accepted Answer

The hour/minute/second readout under your target date isn't a pre-baked animation — it's recalculated every second directly from your device's clock against the exact target instant, using a repeating timer that's cleaned up automatically if you switch tabs or navigate away. Because it reads the real current time on every tick rather than counting down from a fixed starting number, it stays correct even if your computer sleeps and wakes back up mid-countdown.

Question 3

Can I use the Days Since tab to track a streak or habit?

Accepted Answer

Yes — plug in the date you started (a quit date, a workout streak, a sobriety milestone, a project kickoff) and the tab reports the exact number of days, weeks, and years elapsed since then, plus which weekday it began on. It's the mirror image of the countdown tab: instead of counting down to a future date, it counts up from a past one, which is the more natural framing for tracking how long you've kept something going.

Question 4

Why do the days-until numbers for Christmas or New Year change every time I check?

Accepted Answer

Each holiday card always points at its next upcoming occurrence, not a fixed date — so a holiday that already passed this year automatically rolls forward to next year's date the moment it's in the past. That's why the countdown to, say, Halloween keeps shrinking day by day until October 31st, then immediately jumps back up to roughly 365 the following morning.

Question 5

How do leap years affect a day counter?

Accepted Answer

A leap year adds a 366th day (February 29th) roughly every four years, so any countdown or days-since span that crosses a February 29th ends up one day different than a naive "years × 365" estimate would suggest. This calculator never estimates — it works directly off the calendar, so every leap day inside a given span is automatically accounted for without you having to think about it.
