What's the difference between Personal and Studio?

Personal ($39) is for one person — unlimited use on one active device at a time. Activate on a new device and the old one signs out. Studio ($199) is for teams and commercial client work — unlimited team members, early access to new tools, and a commercial license.

Do I need an account?

No. Use any tool free up to 5 times per day on compute-heavier tools, and unlimited on lightweight ones. No card, no account, no signup required.

Where are my files processed?

Right on your device. Files never upload to any server. Everything runs in your browser — you can verify in DevTools → Network.

What happens if I use my Personal license on a second device?

The new device activates and the old device signs out. Your license key stays the same — you just move it between devices as needed. No limit on how often you switch.

Does this work on my phone?

Yes. Every tool works on iPhone, Android, tablet, and desktop.

What if I want a refund?

30-day money-back guarantee on both tiers. No questions asked. Email sales@cipherforces.com.

Will you add more tools?

Yes. New tools ship regularly. Your license includes every tool we ever release — Studio members get early access.

Calculate an Exact Age — Down to the Day

Enter a date of birth and get the precise age in years, months, and days, measured as of today or any past or future date you choose. The same result also breaks the span down into total months, weeks, days, hours, minutes, and seconds, tells you which weekday you were born on, and counts down to the next birthday. A second mode finds the exact gap between any two dates, including full weeks and the number of business days.

Everything is computed on your device using the browser's own calendar — nothing is uploaded, there's no sign-up, and there are no usage limits. The math is done on whole dates rather than timestamps, so results never drift by a day for people in evening or negative-offset timezones, and total-day counts are measured against UTC midnights so a daylight-saving change can't throw them off.

One honest caveat: because the calculator works from calendar dates and not a specific clock time, the hour, minute, and second totals assume midnight-to-midnight. They're exact multiples of a whole day, not a live tick from your exact moment of birth.

Common Use Cases

Eligibility checks: Confirm someone meets an age requirement — a license, a discount, a benefit, or a school cutoff — as of a specific date.
Forms and applications: Fill in an exact age in years and months for medical intake, immigration, or insurance paperwork.
Milestones and birthdays: See how many days until the next birthday and what day of the week it lands on, so you can plan ahead.
Notice periods and deadlines: Use days-between to count the exact span from a start date to a due date, contract end, or 30/60/90-day deadline.
Project and leave planning: Get the business-day count (Monday–Friday) between two dates, separate from weekend days.
Pets, anniversaries, and records: Track how old a pet is, how long since an anniversary, or the age of a document in weeks and months.

Privacy: The age calculator runs entirely in your browser. The dates you enter never leave your device, are never sent to a server, and are not stored anywhere.
