Is 1 hour too long for a single study session?

Not for deep learning. While the Pomodoro (25 min) is good for tasks with low resistance, a 1 hour timer is better for complex problem-solving or essay writing where 'getting into the zone' takes at least 15-20 minutes.

How many minutes are in 1 hour?

There are 60 minutes in 1 hour. In terms of seconds, that's 3,600 seconds. Using a 60-minute countdown helps students and professionals time-box large-scale projects into manageable units.

Why do Korean students use 1-hour timers?

In the 'Study With Me' (공방) community, the 1 hour study timer is the gold standard. It reflects a high level of discipline and is often used to prepare for intense exams like the CSAT (Suneung). AFFiNE supports this by providing a secure, local-first space to store all exam-related knowledge.
