About the Age Calculator
The Age Calculator tells you exactly how old you (or anyone else) are right now, expressed in years, months, weeks, days, hours and even minutes. It also counts down to your next birthday and shows useful UK milestones along the way. Enter your date of birth, choose a calculate-as-of date (defaulting to today), and the calculator does the rest, automatically handling leap years and varying month lengths so the answer is accurate to the day.
Knowing your exact age is more useful than it sounds. It matters for legal thresholds (alcohol sales, voting, driving), for accessing financial products (the Lifetime ISA closes to new contributions at 50, private pensions become accessible at 55 rising to 57 from April 2028, and the State Pension currently starts at 66), and for medical screening invites (cervical screening from 25, breast screening from 50, bowel screening from 50, NHS health check at 40). The calculator is also helpful for HR and recruitment, school admissions, sporting age groups, and pet-age conversions.
UK-specific age milestones built into the calculator include the State Pension age (currently 66, rising to 67 by April 2028 and to 68 between 2044 and 2046), the minimum pension access age (55 now, 57 from April 2028), the school starting age (the September following the 4th birthday in England), and the eligibility ages for the English National Concessionary Travel Scheme (free off-peak bus travel from State Pension age) and the London Older Persons Freedom Pass (age 60+).
The calculator also computes how many days you have been alive — a 30-year-old has typically lived around 10,958 days — and shows fun milestones like your 10,000th day (around age 27 years 4 months) and 30,000th day (around age 82). For relationships and family planning, it can compare ages between two people to show exact age gaps, which is useful for understanding sibling or partner age differences with month-and-day precision.
How to use this calculator
1
Enter the date of birth
Pick your date of birth from the date picker, or type it in DD/MM/YYYY format. The calculator accepts any date from 1 January 1900 onwards.
2
Choose the comparison date
By default the calculator uses today. Change it to find your age at a future or past event — for example, your age on your next holiday or at a particular wedding.
3
Review the breakdown
See your exact age in years, months and days; total months, weeks, days, hours and minutes; and the day of the week you were born on.
4
Check upcoming milestones
The calculator highlights the next UK milestone (e.g. private pension access at 55, State Pension at 66) and the days remaining until your next birthday.
5
Compare ages
Use the optional second date of birth field to calculate the exact gap between two people, expressed in years, months and days.
Common mistakes to avoid
!Confusing CPI and RPI — UK official measure is CPI since 2010; RPI usually ~0.8pp higher but legacy use only (rail fares, student loans pre-2023).
!Calculating percentage increase vs decrease incorrectly — a 50% rise then 50% fall does NOT return to start (it leaves you 25% down).
!Treating UK and US pints/gallons as interchangeable — UK pint 568ml, US pint 473ml. Recipes often need conversion.
!Ignoring leap years in date-difference calculations — important for SDLT 3-year reclaim window and CGT 60-day reporting.
Enter your date of birth and our calculator will work out your exact age in years, months, weeks and days. We also show how many days until your next birthday.
What is the UK State Pension age in 2025?
The State Pension age in 2025 is 66 for both men and women. It is scheduled to rise to 67 between 2026 and April 2028, and to 68 between 2044 and 2046 (a review may bring this forward). Check your personal State Pension age using the gov.uk State Pension age calculator, which factors in your exact date of birth.
At what age can I access my private pension in the UK?
The Normal Minimum Pension Age (NMPA) for accessing a private or workplace pension is currently 55. It rises to 57 from 6 April 2028. Some older pension schemes have protected pension ages of 50 or younger for members who joined before April 2006. Accessing a pension before NMPA without protection triggers a 55% unauthorised payment charge.
When does someone start school in England?
Children in England start primary school in the September following their fourth birthday — so a child born between 1 September and 31 August enters Reception that September. Compulsory school age is the term after the fifth birthday. Summer-born children (April-August) can request to start a year later, kept with their proper academic year throughout schooling.
At what age can I drive in the UK?
You can apply for a provisional driving licence at 15 years 9 months, ride a moped from 16, and take a car driving test from 17 (16 if you receive higher-rate mobility component of DLA or enhanced PIP). Motorcycle ages depend on the bike: A1 (125cc) at 17, A2 at 19 and full A at 24, or after 2 years on an A2 licence.
What age can I vote in UK elections?
You can vote from 18 in UK general elections, English and Northern Irish council elections. Scotland and Wales allow 16 and 17 year olds to vote in Scottish Parliament, Senedd and local council elections, but not UK general elections. To vote you must be on the electoral register and provide photo ID at the polling station for most elections from 2023 onward.
At what age can I buy alcohol in the UK?
You must be 18 to buy alcohol in shops, supermarkets, pubs, bars, restaurants or online in the UK. 16 and 17 year olds may drink beer, wine or cider with a meal in a restaurant if bought by an adult. It is illegal for adults to buy alcohol for under-18s outside this exception. Retailers operate Challenge 25 to verify age.
When do I become eligible for free NHS prescriptions?
In England, NHS prescriptions are free from age 60. Wales, Scotland and Northern Ireland already provide free prescriptions for all ages. Under-16s are also exempt across the UK, as are 16-18 year olds in full-time education, pregnant women, new mothers within 12 months of birth, and people with certain medical conditions or low incomes.
What free TV licence rules apply for older people?
Free TV licences are only available to households where someone aged 75+ receives Pension Credit. The universal free over-75 TV licence ended in August 2020 and now requires the Pension Credit qualifying criterion. A standard colour TV licence costs £174.50 in 2025/26. Households without anyone under 75 still need a licence unless qualifying.
When can I claim a Senior Railcard or Freedom Pass?
You can buy a Senior Railcard from age 60, giving 1/3 off most rail fares for £30/year. The London Older Persons Freedom Pass gives free travel on Transport for London services from age 66 (linked to State Pension age, not 60). Free off-peak bus travel via the English National Concessionary Travel Scheme starts at State Pension age (66).
