Description
Calculate calendar months elapsed since a supplied retirement month.
Aging research distinguishes participant and informant identities, calendar-month coordinates, time-use exposure and event/censoring status. Proxy responses and missing codes carry different meanings from direct observations. Local record summaries do not establish lifespan, legal status, accessibility or appropriate care.
Calculate calendar months elapsed since a supplied retirement month.
When to use this tool
Use Retirement Months Since Event when checking the stated aging-study record, timing, censoring or support convention.
How to use the tool and how it works
- Enter retirementYear, retirementMonth, asOfYear, asOfMonth. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedCalendarMonthOffset. Use the output convention below.
Require whole years 1..9999 and months 1..12. Return 12*(asOfYear-retirementYear)+asOfMonth-retirementMonth.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| retirementYear | Whole year 1..9999; differs from the year-zero-accepting text-month helper. | Required. Safe integer; minimum 1; maximum 9999. |
| retirementMonth | Retirement Month | Required. Safe integer; minimum 1; maximum 12. |
| asOfYear | As Of Year | Required. Safe integer; minimum 1; maximum 9999. |
| asOfMonth | As Of Month | Required. Safe integer; minimum 1; maximum 12. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedCalendarMonthOffset | Signed Calendar Month Offset | Required. Safe integer. |

}Limitations and assumptions
- Negative offsets are retained; month coordinates do not establish retirement status, pension entitlement or an exact elapsed duration in days.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified original records and suitable complete research methods; involve qualified health, accessibility or legal professionals for actual care or rights decisions.
