Calculator and Productivity Tools

Age Calculator

The Age Calculator gives you your exact age in years, months and days — plus some fun life statistics: total days alive, estimated heartbeats, breaths taken, Earth orbits completed and your next birthday countdown. Enter any birthdate to try it with historical figures like Alan Turing or Ada Lovelace.

Time Zone Converter

The Timezone Converter supports all 400+ IANA time zones with full daylight saving time awareness. The world clock shows live current time in 10 major cities — click any city to set it as your target timezone. Common conversion pairs (EST → PST, UTC → PKT, London → Tokyo) are pre-listed at the bottom.

Chmod Calculator

The Chmod Calculator is a visual Unix file permission editor. Click to toggle read, write and execute bits for owner, group and other. The octal code updates instantly alongside the symbolic notation and the exact chmod command to run. Eight presets cover the most common scenarios (755 for scripts, 644 for files, 600 for SSH keys).

Pomodoro Timer

The Pomodoro Timer implements the classic 25-minute focus / 5-minute break cycle with desktop notifications when each phase ends. After 4 sessions it automatically schedules a 15-minute long break. All session timing is configurable from the settings panel. The daily stats panel shows sessions completed, focus minutes and breaks taken.
