Percentage Calculator
Calculate X% of a number, find what percent one value is of another, reverse a percentage, compare percentage change, and work out percentage difference, discounts, increases, and decreases.
Age Calculator
Calculate exact age in years, months, days, and total days from a birth date and an as-of date.
Date Calculator
Calculate days between dates, or add and subtract years, months, weeks, and days from a date.
Time Duration Calculator
Calculate same-day time differences or add multiple hours-and-minutes durations.
Unit Converter
Unit Converter supports metric, imperial, and US unit conversion across 13 categories including length, weight, temperature, area, volume, time, speed, pressure, energy, power, storage, angle, and frequency.
Timestamp Converter
Timestamp Converter supports bidirectional conversion between Unix timestamps and dates, auto-detects seconds or milliseconds, and includes local, UTC, and city timezone views for logs, debugging, and database work.
World Clock
World Clock supports tracking local time across multiple cities, handles daylight saving changes automatically, and offers digital and analog displays for meetings and cross-timezone planning.
UUID Generator
