Last updated: 2026-10-25

> The every second calculator shows what happens in the world while time passes: babies born, Google searches, emails sent, lightning strikes, video uploaded, and how far Earth and light travel – in a second, minute, hour or any period.

## Inputs

- Time period (s, min, h, days, years)

## Results

- Babies born worldwide
- Deaths worldwide
- Google searches
- Emails sent
- YouTube video uploaded
- Lightning strikes
- Your heartbeats (≈ 72 per minute)
- Distance Earth travels around the Sun
- Distance light travels

## Formula

```
Total = rate per second × number of seconds in the period
```

## Explanation

Statistics expressed per second help make huge yearly numbers easier to imagine. The figures are recent worldwide estimates and averages – actual rates vary by time of day and season.

### How to use the Every Second Calculator – What Happens in a Second

- **Time period**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter a length of time and its unit.

### Tips

- Check whether the end date should be included – event durations usually include it, elapsed time does not.
- Months have 28–31 days, so "one month" is counted by calendar date, not as 30 days.
- Use 24-hour time or set AM/PM carefully when entering clock times.
- Time zones and daylight-saving changes are not applied unless the calculator says so.

### Common mistakes to avoid

- Counting a 30-day month when a calendar month is meant (or the reverse).
- Forgetting leap years when counting days across February.
- Mixing decimal hours (7.5 h) with clock time (7:30).

### What each result means

- **Babies born worldwide** = [Time period]×4.3
- **Deaths worldwide** = [Time period]×2.0
- **Google searches** = [Time period]×99000
- **Emails sent** = [Time period]×4000000
- **YouTube video uploaded** = [Time period]×500÷60
- **Lightning strikes** = [Time period]×44
- **Your heartbeats (≈ 72 per minute)** = [Time period]×1.2
- **Distance Earth travels around the Sun** = [Time period]×29.78
- **Distance light travels** = [Time period]×299792.458

### Example values

How the main result changes when **Time period** changes and everything else stays at the example values above:

## Worked example

Inputs — Time period: 1 s.

Results — **Babies born worldwide = 4.3**; Deaths worldwide = 2; Google searches = 99,000; Emails sent = 4,000,000; YouTube video uploaded = 8.3 hours; Lightning strikes = 44; Your heartbeats (≈ 72 per minute) = 1.2; Distance Earth travels around the Sun = 29.8 km; Distance light travels = 299,792 km.

## FAQ

**How many babies are born every second?**
About 4.3 worldwide – roughly 370,000 a day.

**How many Google searches happen every second?**
Roughly 99,000, or 8.5 billion a day.

**How fast does Earth move around the Sun?**
About 29.8 km (18.5 miles) every second.

**What formula does the Every Second Calculator – What Happens in a Second use?**
Total = rate per second × number of seconds in the period.
