Frequently Asked Questions

How long should my password be?

At least 16 characters. Length matters more than complexity — a 16-character random password is stronger than an 8-character one with symbols. Use our password generator and a password manager.

How do I calculate days between two dates?

Enter the start and end dates in our date calculator. It accounts for leap years and month-length variations. Useful for project deadlines, event planning, and age calculations.

What's the difference between a stopwatch and a timer?

A stopwatch counts up from zero (timing how long something takes). A countdown timer counts down from a set time (tracking remaining time until an event). Our tools support both modes.
