Plan Your Week, Then Let Rize Track It
Build your ideal schedule here, then see how closely you follow it. Rize tracks your actual time automatically and shows where it goes.
How to Structure Your Work Day
Research shows that the structure of your workday matters more than the total hours you put in. Here is how to build a schedule that maximizes productive output.
Set your target hours
Most knowledge workers produce 4-6 hours of focused work per day, regardless of how many hours they spend at their desk. Set a realistic target and protect those hours.
Use focus blocks
Work in 60-90 minute blocks of uninterrupted focus, then take a short break. This aligns with your body's natural ultradian rhythm and produces higher quality output than continuous work.
Schedule breaks deliberately
Place your lunch break near the midpoint of your work day and take short breaks between focus blocks. The DeskTime study found that the most productive workers work 52 minutes then break for 17.
Track and adjust
Your planned schedule is a hypothesis. Track your actual time for a week, compare against the plan, and adjust. Rize does this automatically, showing you where your real hours go.

Frequently Asked Questions
Research from Stanford University shows productivity drops sharply after 50 hours per week, and output at 70 hours is roughly the same as at 56 hours. For knowledge workers, 35-45 productive hours per week is the sweet spot. What matters more than total hours is how those hours are structured.
The most productive schedule uses 60-90 minute focus blocks with short breaks in between. The DeskTime study of 5.5 million work records found that top performers work 52 minutes then break for 17. The key is protecting focus time from interruptions, not maximizing hours at your desk.
Utilization rate is the percentage of your total time at work spent on productive tasks. Divide productive hours by total hours (including breaks and administrative time). An 80% utilization rate means you spend 80% of your work day on productive tasks and 20% on breaks and overhead.
A compressed work schedule fits the standard 40-hour workweek into fewer days. The most common is 4x10 (four 10-hour days), giving employees a three-day weekend. Some organizations use 9/80 (alternating 4-day and 5-day weeks with 9-hour days). Research shows compressed schedules can improve job satisfaction without reducing output.
Short breaks between focus blocks should be 5-15 minutes. Your main lunch or meal break should be 30-60 minutes. The Pomodoro Technique uses 5-minute breaks after 25-minute work sessions and a 15-30 minute break after four sessions. Longer focus blocks (90 minutes) call for slightly longer breaks (15-20 minutes).
Deep work is focused, uninterrupted cognitive effort on demanding tasks. Cal Newport's research suggests most people can sustain 3-4 hours of deep work per day (beginners start at 1 hour). Schedule deep work during your peak cognitive hours, typically in the morning, and protect those blocks from meetings and interruptions.
Decide your total weekly hours (20 is standard for half-time), then divide by the number of days you want to work. A 20-hour week over 4 days gives 5-hour days; over 5 days gives 4-hour days. Part-time workers should still use focus blocks and scheduled breaks to maintain productivity per hour worked.
Automatic time tracking software like Rize records your actual work hours in the background and categorizes them by app, website, and project. Compare your planned schedule from this calculator with your actual time data in Rize to see where your time goes and how closely you follow your plan.
