Free online time & date tools
Gizmoop's time and date tools gather the everyday time jobs into one place: figuring out exactly how old someone is, counting down to a date that matters, and carving your day into focused work blocks. Each one runs instantly in your browser - no signup, no upload, and no waiting on a server.
Three core tools live here. The Age Calculator turns a date of birth into an exact age, your Countdown Timer runs a live countdown to any future event, and the Pomodoro Timer keeps you focused with classic 25/5 cycles. From this hub you can also jump straight to related utilities for date math, durations, work hours, and time zones.
Everything is built to be accurate first. Leap years, varying month lengths, and daylight saving time are handled for you, so the numbers you see are the numbers you can trust - whether you are planning an event or planning your week.
Age Calculator - your exact age in years, months & days
The Age Calculator answers a deceptively tricky question: exactly how old am I right now? Enter a date of birth and it works out the precise difference to today, breaking it into complete years, remaining months, and leftover days - and it can also show your age in total weeks, days, hours, and minutes for the curious.
Getting that right is not as simple as subtracting years. Months have 28 to 31 days, leap years add a February 29, and a naive calculation drifts by a day or more. The exact age calculator handles all of it, counting forward month by month so the result is correct on any date, including the day after a birthday.
Beyond raw age, it finds your next birthday and counts the days until it arrives, picking this year if the date is still ahead or next year if it has already passed. It also labels your generation - from Baby Boomer through Gen X, Millennial, Gen Z, and Gen Alpha - straight from your birth year, so you get age, countdown, and generation in one place.
Countdown Timer - a live countdown to any date
A countdown reframes a far-off date as something concrete: not just March 14, but 47 days, 6 hours, and 12 minutes away. The Countdown Timer lets you pick any future date and time, give the event a name, and watch a live countdown to any date tick down in days, hours, minutes, and seconds right in the page.
Setting one up takes seconds. Choose the target date and time, optionally label it - Product Launch, Final Exam, Wedding - and the timer starts counting immediately and keeps updating in real time as long as the tab is open. It is the simplest way to make a deadline feel real instead of abstract.
People reach for a live countdown timer for all kinds of moments: counting down to a birthday or holiday, building anticipation for a product launch or sale, tracking a project deadline, or marking the new year. Anything with a fixed date on the calendar becomes a tidy, shareable countdown.
Pomodoro Timer - 25/5 focus cycles that beat procrastination
The Pomodoro Timer applies a proven time-management method to your screen. You work in focused 25-minute intervals called pomodoros, take a 5-minute break after each one, and after four pomodoros take a longer 15 to 30 minute break. That rhythm turns a vague to-do list into a series of short, winnable sprints.
The technique, created by Francesco Cirillo in the late 1980s, works because 25 minutes is long enough to get into deep focus but short enough that starting never feels daunting - and the frequent breaks keep attention fresh and head off burnout. Knowing a break is minutes away makes it far easier to ignore distractions and just begin.
Gizmoop's online Pomodoro timer shows the remaining time right in the browser tab title, so you can switch to your work in another tab and still see the countdown at a glance. The intervals are adjustable, so if 25/5 is not your sweet spot you can tune the focus and break lengths to fit how you work.
Time management & productivity - getting more from your day
These tools are more useful together than apart. The Pomodoro Timer protects your attention in the moment, while a countdown keeps the bigger deadline in view - pairing a steady work rhythm with a visible finish line is a simple, effective way to beat procrastination and ship the thing.
A practical routine: set a Countdown Timer to your real deadline so urgency stays front of mind, then run Pomodoro sessions to chip away at the work in focused blocks. Between sprints, a quick break resets your concentration far better than powering through until you stall.
If your day involves writing or speaking, the reading time calculator estimates how long a piece takes to read aloud or silently - handy for sizing a talk, a script, or a study session before you start a Pomodoro on it. Small time-savers like these add up across a week.
Need to do date math? Use our Date Calculator
When you need to count rather than count down, reach for the date calculator. It finds the exact number of days between two dates - useful for tracking a deadline, a notice period, or simply how long ago something happened - and can count business days only when weekends should not be included.
It also runs date math in the other direction: add or subtract days from a date to find a due date 90 days out, a return date two weeks from now, or any milestone offset from a starting point. Like the Age Calculator, it handles leap years and month lengths so the result is always accurate.
Reach for it whenever the question is about the gap between dates - days between two dates, a project timeline, or a what-day-will-it-be calculation - rather than a live ticking countdown to a single event.
Add & subtract time with the Time and Hours Calculators
Working with durations rather than calendar dates? The time calculator lets you add and subtract time in hours, minutes, and seconds, and convert the total to decimal hours - exactly what you need for summing lap times, session lengths, or any stack of durations that does not fall neatly on the clock.
For work and pay, the hours calculator figures out the hours between two times, including overnight shifts that cross midnight, and can total a full week. Feed it your clock-in and clock-out times, optionally subtract a break, add an hourly rate, and it returns total work hours and gross pay - no spreadsheet required.
Between the two, you have duration math covered: the Time Calculator for raw durations and unit conversions, and the Hours Calculator for shift hours, timesheets, and work-hours-to-pay. Both are a click away whenever the clock, not the calendar, is what you are adding up.
Working across time zones? Try the Timezone Converter
Scheduling across cities is where time math gets genuinely error-prone, because daylight saving shifts change the offset between zones a few times a year. The timezone converter handles that for you, letting you convert time between time zones with DST applied automatically so 3 PM in New York lands on the correct local hour in London, Karachi, or Tokyo.
It doubles as a meeting planner: line up several cities side by side and find a slot that works for everyone without doing offset arithmetic in your head. Pick a time in one location and read off the matching time everywhere else at a glance.
If you regularly coordinate calls, deadlines, or releases with people in other regions, the Timezone Converter removes the single most common scheduling mistake - getting the hour wrong because someone forgot a clock had changed.
How to choose the right time tool
The quickest way to pick is to name the task. Want to know how old you or someone else is, or how long until a birthday? That is the Age Calculator. Counting down to a single fixed event? The Countdown Timer. Trying to focus and stop procrastinating? The Pomodoro Timer.
If the question is about the gap between two dates or a due date, use the Date Calculator. For adding or subtracting durations, the Time Calculator; for shift hours and pay, the Hours Calculator. To schedule across regions, the Timezone Converter, and to size how long something takes to read or present, the reading time calculator.
The comparison table below maps each tool to what it does and what it is best for, so you can scan it and land on the right one in a few seconds.
Why use Gizmoop's time & date tools

Frequently asked questions
If you don't find your question here, ask us directly.
Enter your date of birth in the Age Calculator and it finds the precise difference to today, accounting for leap years and the different lengths of each month. It breaks the result into complete years, remaining months, and leftover days, and can also show your age in total weeks, days, and hours.
The Age Calculator finds the next occurrence of your birth date - this year if it has not passed yet, otherwise next year - and counts the days until it automatically. There is no manual leap-year math; the countdown updates based on today's date.
The common bands are Baby Boomers (1946-1964), Gen X (1965-1980), Millennials (1981-1996), Gen Z (1997-2012), and Gen Alpha (2013 onward). The Age Calculator labels your generation automatically from your date of birth alongside your exact age.
Open the Countdown Timer, pick your target date and time, and optionally give the event a name. It immediately starts a live countdown showing the days, hours, minutes, and seconds remaining, updating in real time while the tab is open.
The Pomodoro Technique is a time-management method created by Francesco Cirillo that breaks work into focused 25-minute intervals called pomodoros, each followed by a 5-minute break. After four pomodoros you take a longer 15 to 30 minute break. The structure reduces interruptions and makes it easier to start and sustain focus.
Twenty-five minutes is long enough to reach deep focus but short enough to avoid burnout, and the 5-minute break gives your attention time to reset before the next sprint. The cycle is a starting point, not a rule - the timer's intervals are customizable if a different rhythm suits you.
Yes, every tool here is completely free with no signup, no email, and no daily limit. They run in your browser and the calculations happen on your device, so your inputs are private and you can start using any tool the moment it opens.
A countdown timer counts down once to a fixed future date or event, like a birthday or launch. The Pomodoro timer runs repeating fixed-length focus and break intervals to help you work productively. Use the Countdown Timer for a single deadline and the Pomodoro Timer for ongoing focus sessions.
