How to use these calculators
Four steps, no account and nothing to upload.
Step 1: Open the calculator
Each card says exactly what it works out, so you can match it to the line on your form before you start typing.
Step 2: Enter your dates
Type them or pick them from the calendar. Everything stays on your device — there is no upload and no account.
Step 3: Set the date it counts from
Recruitment notifications fix eligibility “as on” a particular day. Enter that date and you get the figure the form will actually use.
Step 4: Read or copy the answer
The result appears instantly, broken down unit by unit, and copies to your clipboard with one tap for pasting into a form.
Why applicants use these calculators
Because “age as on 01/01/2027” is easy to get wrong by a month and expensive to get wrong at all.
Built around the cut-off date
SSC, UPSC, Railway, IBPS and state PSC notifications judge eligibility on a fixed date, not on the day you apply. Every calculator here lets you set that date yourself.
Exact, never rounded
Completed years, then months, then the days left over — the way an age is written on an application. Leap years and real month lengths are handled properly.
Nothing leaves your device
The arithmetic runs in your browser. Your date of birth is not uploaded, not logged and not stored anywhere.
Free and unlimited
No sign-up, no daily cap, no charge — check as many dates and combinations as you need.
Works on any device
Android, iPhone, tablet or desktop. The pages are light enough to load and work on a slow connection.
Answers you can paste
Every result is real text, laid out the way a form wants it, so it can be copied straight across instead of retyped.
Frequently asked questions
What people ask before trusting a number to an application form.
What calculators are available here?
Three are live. The Age Calculator gives your exact age in years, months and days on any date you choose, along with the total months, weeks, days, hours and minutes, a countdown to your next birthday and the day of the week you were born on. The Percentage Calculator works out what is X% of a value, what percent one number is of another, a percentage increase or decrease, and the difference between two figures. The Marks Percentage Calculator turns marks into a percentage — from your mark sheet totals or subject by subject — with the grade, division, pass or fail and CGPA equivalent. More calculators for Indian government job applicants are being added to this hub.
How do I calculate my marks percentage for an application form?
Add up the marks you scored across every subject, add up what those subjects were out of, then divide the first total by the second and multiply by 100 — 432 out of 500 is 86.4%. The Marks Percentage Calculator does both steps for you and shows the grade, division, pass or fail and CBSE CGPA equivalent beside the figure. Do not average your subject percentages unless every paper carries the same total, as that weights a 50-mark paper the same as a 100-mark one.
Why does the “age as on” date matter so much?
Almost every Indian recruitment notification fixes an age limit as on a particular day — commonly 1 January, 1 July or 1 August of the exam year — and your age on that day is what decides eligibility, not your age on the day you fill the form in. A few months either side of a cut-off can be the difference between qualifying and not, which is why the date is something you set yourself here rather than something the tool assumes.
Are these calculators free to use?
Yes, completely. There is no sign-up, no email address to hand over, no daily limit and no charge. The site is funded by advertising, which is why you may see ad space below a tool — never over it.
Is anything I type stored or uploaded?
No. Unlike the image and PDF tools, which send a file to a server to be processed, the calculators do all their work inside your browser. Nothing you type is transmitted, logged or stored, and it is gone as soon as you close the tab.
Do the calculators work on a phone?
Yes. Every calculator is fully responsive and works in any modern browser on Android and iOS, with the native date picker on the fields that take a date. Once the page has loaded, the calculation itself works even if your connection drops.
Can I rely on the result for an official form?
The arithmetic is exact — completed years, months and days, with leap years counted properly — and it is the same method an application form uses. What no calculator can tell you is the age limit for your post and category, which changes by exam and by year, so always check the figure against the criteria in the official notification.
