How your retirement date is calculated
Your retirement date is the day you reach the retirement age you choose: your date of birth plus that many years (and months, if you add them). The calculator counts real calendar dates, then shows the time left in years, months and days, plus the total in months, weeks, days and weekdays, and how many birthdays you have to go.
If you were born at the end of a month and the age includes extra months, the date can land on a day that doesn’t exist, such as 31 June. In that case the calculator uses the last day of the month, just as it does for ages; our methodology explains the rule.
Official pension ages (as of October 2026)
There’s no single retirement age. Most countries set an age from which a state pension is paid, and many people retire earlier or later than that. These are the headline ages in some English-speaking countries:
| Country | Pension | Age |
|---|---|---|
| United States | Social Security full retirement age | 67 if born in 1960 or later; reduced benefits from 62 |
| United Kingdom | State Pension | 66, rising to 67 for people born from 6 April 1960 (phased in 2026–2028) |
| Canada | Old Age Security; Canada Pension Plan | OAS from 65; CPP from 60 to 70 (standard age 65) |
| Australia | Age Pension | 67 for people born on or after 1 January 1957 |
Pension rules change, and eligibility usually depends on more than age, such as contribution records, residence, or income and assets tests. Always confirm your own date with the official source: the US Social Security Administration, GOV.UK, the Government of Canada or the Australian Department of Social Services.
Retiring early or late
Choosing when to start a pension often changes how much you receive. In the US, claiming Social Security at 62 when your full retirement age is 67 reduces your monthly benefit permanently, by up to about 30%, while delaying past full retirement age earns credits until 70. In the UK you can defer your State Pension to get more later. Other schemes, including workplace and private pensions, have their own rules.
That’s why it helps to try several ages. Use the quick buttons (60, 62, 65, 66, 67, 70) to compare dates and countdowns side by side as you plan.
Planning with your countdown
A few figures from the calculator are especially useful when you plan:
- Weekdays left, a rough upper limit on your remaining working days.
- Birthdays to go, a friendlier way to picture the time.
- Progress, the share of the time from birth to retirement that has already passed.
The years left to retirement are also your investing horizon. If you save through monthly mutual fund SIPs, enter them in the goal SIP calculator on Sipculator to see how much you’d need to invest each month to reach a retirement target.
This calculator only does date arithmetic. It isn’t financial advice and doesn’t know your pension entitlements. For decisions about money, talk to your pension provider or a qualified adviser. For other age-based rules, from voting to driving, see our guide to legal ages around the world.

Frequently asked questions
When can I retire?
That depends on your country, your pension scheme and your finances. Many state pensions are paid from an age between 65 and 67. Enter your date of birth and the age that applies to you, and the calculator shows the exact date you reach it and how long you have left.
What is the full retirement age in the United States?
For Social Security, full retirement age is 67 for anyone born in 1960 or later. You can claim from 62 with a permanently reduced benefit, or delay to as late as 70 for a larger one. Check your own figures at ssa.gov.
What is the State Pension age in the UK?
It has been 66 and is rising to 67 for people born on or after 6 April 1960, phased in month by month between 2026 and 2028. Your exact date depends on your date of birth, so check it with the official GOV.UK State Pension age calculator.
How many working days do I have left before I retire?
The Countdown card shows the weekdays (Monday to Friday) between today and your retirement date. It doesn’t subtract public holidays or annual leave, so your real number of working days will be lower.
Can I enter a retirement age like 66 and 4 months?
Yes. Enter the years and the extra months separately, for example 66 years and 4 months. The quick buttons fill in common ages in whole years.
