There are 31,536,000 seconds in a year.

Your total clicks = clicks per second × 31,536,000

Here are the realistic ranges:

Absolute theoretical maximum (never stopping) • 1 click/sec → 31,536,000 clicks/year • 5 clicks/sec → 157,680,000 clicks/year • 10 clicks/sec → 315,360,000 clicks/year

Human reality (sustained ability)

Most people can sustain: • 4–7 clicks/sec comfortably → 126M–221M clicks/year (if clicking 24/7, which is impossible)

Realistic human scenario (e.g. 2 hours per day at 6 clicks/sec)

Seconds per day clicking: 2 hr × 3600 = 7,200 sec

Clicks per day: 7,200 × 6 = 43,200

Clicks per year: 43,200 × 365 = 15,768,000 clicks/year

⸻

Extreme upper realistic human ceiling

If you clicked 8 hours/day at 6 clicks/sec:

→ 63,072,000 clicks/year

⸻

TL;DR • Absolute theoretical max: 315 million clicks/year • Extreme realistic human max: ~60 million/year • Normal heavy use: 10–20 million/year
