Baby vaccination schedule calculator
A vaccination schedule calculator turns your baby’s date of birth into real calendar dates for every immunisation visit. Enter the date of birth, pick the schedule your clinic follows, and you get 9 dated visits covering 27 doses, what is due now, what is overdue, and the earliest valid date for anything that was missed.
Stays in your browser. Nothing is uploaded or stored.
Free at government health facilities. See the full schedule
Enter a date of birth to see every visit as a real date.
How it works
- 01
Enter the date of birth
The one input the whole schedule is built from. It stays in your browser.
- 02
Pick the schedule you follow
Government UIP or the IAP schedule most private clinics use in India.
- 03
Mark what is already done
Optional, and it turns the result into a list of only what is still left.
- 04
Read the dates, then print them
Every visit as a real date, with catch-up dates for anything overdue.
What the catch-up dates mean
A missed dose is common and rarely serious. Childhood schedules set the earliest age a dose works well, not a deadline, so a series that fell behind is almost always resumed rather than restarted.
Two rules decide when a late dose can be given: the minimum age for that dose, and the minimum gap since the dose before it. The calculator applies both and shows the later of the two, which is the earliest date the dose can validly be given. It is an earliest date, not a recommendation: your pediatrician decides the actual appointment.
A small number of vaccines do close. Rotavirus is the clearest case, as the series is not started or continued past about eight months. Where a dose is past that age the calculator says the window has closed instead of calling it overdue, because the two need different conversations with your doctor.
Pick your country
Each country page carries that country’s full schedule, what the vaccines cost and where to get them, and the same calculator set up for it.
India immunization schedule
India runs two childhood vaccination schedules.
Open →United States immunization schedule
The United States childhood immunization schedule is set by the CDC with the Advisory Committee on Immunization Practices, and published alongside a harmonised schedule from the American Academy of Pediatrics that pediatric practices follow..
Open →United Kingdom immunisation schedule
The UK childhood immunisation schedule is the NHS routine programme, offered free to every child, running from the 8 week appointment through to the teenage boosters..

Every dose in the calculator links to a plain-language page on that vaccine: what it protects against, how it is given, and what to expect afterwards.
Questions parents ask
How does the vaccination schedule calculator work?
- You enter your child’s date of birth and choose the schedule you follow. The calculator adds each visit age in the schedule to that date of birth, so “6 weeks” becomes an actual calendar date. It then compares every date with today to show what is done, what is due now, and what is overdue.
Is my baby’s date of birth stored anywhere?
- No. The whole calculation runs inside your browser. The date of birth is never sent to a server, and nothing is saved to an account. If you copy the link, the details travel inside that link and nowhere else, so only the people you send it to can see it.
What if we missed a vaccine or a whole visit?
- Mark the doses that are already done and the calculator switches to catch-up mode. For each missed dose it works out the earliest date it can validly be given, using the minimum age for that dose and the minimum gap from the dose before it. A missed dose almost never means starting the series again.
Can vaccines be given late?
- Most can. Childhood schedules are designed with the earliest safe age in mind, not a deadline, so a dose given a few weeks or months late still counts and still protects. A few vaccines do have an upper age limit, rotavirus being the clearest example, and the calculator flags those separately rather than listing them as simply overdue.
Which schedule should I choose, UIP or IAP?
- Choose the one your clinic follows. UIP is the Government of India programme, given free at public health facilities. IAP is the Indian Academy of Pediatrics schedule, widely followed in private practice, and it uses more combination vaccines so your child receives fewer injections. Both protect against the same core diseases.
Does the calculator account for premature birth?
- Vaccination timing follows chronological age, the date your baby was actually born, not a corrected age. So a baby born early is vaccinated on the same calendar schedule as a baby born at term. Enter the real date of birth. Very low birth weight can occasionally change the first doses, so confirm with your pediatrician.
Can I print the schedule or save it as a PDF?
- Yes. Print or save as a PDF gives you a one page record with every visit, its date, and the vaccines due, which you can keep in your child’s health folder or take to an appointment.
TinyDose keeps this schedule for you and reminds you before every visit.
Free on iOS and Android.
