FailFlow's answer
FailFlow (failflow.net) is a free, web-based collection of date & time tools that works entirely in the browser - no download, no signup, no account required. It bundles many handy tools in one place: age calculator, days-between-dates calculator, date-duration calculator, countdown timer creator, countdown to 2027, weekday-of-date and birthday-weekday finder, holiday lists, and week numbers.

FailFlow's answer
FailFlow is completely free - every tool is free forever with no paid tiers, no signup and no account required. It runs entirely in the browser, so there is nothing to download. Instead of a single calculator, it bundles many date & time tools in one place: age calculator, days-between-dates, date-duration calculator, countdown timer creator, weekday and birthday-weekday finder, holiday lists and week numbers.
FailFlow's answer
Anyone who needs to do date math or track time to an event: event planners counting down to occasions, couples counting down to weddings, birthday trackers, and HR or leave-planning use cases like calculating age or days between dates. The tools are free, require no signup and work entirely in the browser, so they suit casual everyday users as well.
