Calculate time differences, days between dates, business days, age, and countdown timers. Perfect for project planning, scheduling, and time management.
The Date & Time Calculator on sourcecodestack computes the exact duration between any two points in time, entirely in your browser. Switch between five modes — Date & Time, Date Only, Time Only, Age Calculator, and Countdown — to get the specific breakdown you need. Results update instantly as you type, showing years, months, days, hours, minutes, and seconds alongside a total-seconds summary.
The calculator also supports business-day filtering: toggle the Business Days switch to exclude weekends from the count, and configure whether your working week starts on Monday or Sunday. Quick Presets let you load common scenarios like time remaining until midnight, a 7-day difference, an age calculation from a birth date, or a New Year countdown with one click.
