Utility Tools for Dates, Text, and Design
These 17 tools cover the practical utility tasks that don't fit neatly into other categories — from counting down to a special date, to converting a hex colour code for a web project, to checking whether your password is strong enough.
Date & Calendar Tools
Days Until Date counts the exact number of days remaining to any future event. Weekday Finder tells you which day of the week any date falls on. Leap Year Checker confirms whether a given year has 366 days. Unix Timestamp Converter converts between human-readable dates and Unix epoch timestamps — essential for developers. Work Days Calculator counts business days between two dates, optionally excluding public holidays. Calendar Date Calculator adds or subtracts a number of days from any date.
Text Tools

Text Reverser reverses a string character by character. Palindrome Checker tests whether a word or phrase reads the same forwards and backwards. Lorem Ipsum Generator produces placeholder text in any word or paragraph count for mockups and designs.
Color & Other Tools
