Two dates drive a federal pension case before any money is calculated: the date service ends and the length of service on that date. Both follow fixed conventions, and small differences in either can add or remove a year from the pension formula. This guide walks through them with dates checked in Calculation Guide's Age / Service Calculator.
Why service ends the day before your birthday
Section 13 of the Civil Servants Act 1973 retires a civil servant on completing 60 years of age. CSR Article 14 treats the day on which a retirement age is attained as a non-working day, so the last day of service is the day before the 60th birthday. The Establishment Division's pension guide gives the example: born 1 April 1957, retired 31 March 2017.
| Date of birth | 60th birthday | Last day of service |
|---|---|---|
| 1 April 1957 | 1 April 2017 | 31 March 2017 |
| 1 January 1966 | 1 January 2026 | 31 December 2025 |
| 1 July 1968 | 1 July 2028 | 30 June 2028 |
| 29 February 1968 | 29 February 2028 | 28 February 2028 |
| 10 March 1975 | 10 March 2035 | 9 March 2035 |
A birth on the first of a month moves retirement into the previous month, and a 1 July birthday ends service on 30 June, the last day of the financial year. A 29 February birth is less awkward than it looks: 60 is a multiple of four, so the 60th birthday is normally also a 29 February. Only a different retirement age raises the common-year question; the calculator then takes 28 February as the birthday, so at 63 the same person would retire on 27 February 2031.
Counting service to the day
- Start on the date you took charge of your first regular appointment, as recorded in your service book.
- Move that start later by any days that do not count, such as extraordinary leave without pay.
- Count to the last day of service with both end days included, in completed years, then months, then days.
- For an ordinary pension, add one year if the months left over are six or more. Then cap the result at 30 for the formula.
Including the last day is not a technicality. Calculation Guide counts both end days, so service from 1 January 1999 to 30 June 2028 is 29 years 6 months 0 days. Counted without the final day, it would be 29 years 5 months 29 days, and the six-month rule would no longer add the 30th year. If your accounts office's figure is one day short of yours, check which convention it used before assuming a pension year is lost.
The six-month rule in step 4 comes from the pension rules' condonation of a shortfall of up to six months. It is generous at exactly six months: 29 years 6 months 0 days becomes 30 years. Voluntary retirement does not get this rounding at all.

Consider two officers born on 10 March 1975, both retiring on 9 March 2035. One took charge on 1 September 2006, the other on 11 September 2006.
| Joining date and leave | Total service | Pension years | Gross pension at 7/300 |
|---|---|---|---|
| 1 September 2006, no excluded leave | 28 years 6 months 9 days | 29 | Rs 81,200 a month |
| 11 September 2006, no excluded leave | 28 years 5 months 27 days | 28 | Rs 78,400 a month |
| 1 September 2006, 20 days of extraordinary leave | 28 years 5 months 17 days | 28 | Rs 78,400 a month |
Ten days at the start, or 20 days of unpaid leave mid-career, cost Rs 2,800 a month of gross pension for life. That is why an accurate joining date and leave record in the service book are worth checking years before retirement. How the gross figure turns into a net pension and a commutation lump sum is in the federal 7/300 pension formula.
Where the 30-year cap takes over
Near the top of the scale, the same rounding works against the cap instead. For someone born on 1 July 1968, retiring on 30 June 2028:
| Joining date | Total service | Rounded years | Years in the pension formula |
|---|---|---|---|
| 1 January 1998 | 30 years 6 months 0 days | 31 | 30 |
| 1 January 1999 | 29 years 6 months 0 days | 30 | 30 |
| 2 January 1999 | 29 years 5 months 29 days | 29 | 29 |
Joining on 1 or 2 January 1999 is the difference between the full 70% pension and 67.67%. Joining a year earlier adds nothing, because the formula stops at 30. The same arithmetic applies at the bottom: 9 years 6 months counts as 10 and reaches pension, while 9 years 5 months stays on the service gratuity.
Three rounding rules that look alike
- Ordinary federal pension: six months or more adds a year.
- Voluntary retirement: no rounding; only completed years count, and at least 25 are needed.
- Private-sector gratuity under the Standing Orders: more than six months adds a year, so exactly six months does not. The regimes are compared in gratuity under the Standing Orders and federal rules.
What the dates alone cannot decide
- Which periods qualify: service before regular appointment, breaks, suspension and different kinds of leave are decided from your service book, not by date arithmetic.
- Other retirement ages for particular services, the armed forces, provincial governments or private employers.
- Extensions of service or re-employment after superannuation.
- For a federal employee in the contributory pension arrangement, this page can still find the age-based retirement date. Its qualifying-service year count cannot estimate that employee's pension benefit; check the scheme record for that calculation.
