Queening Date From Mating Calculator
Conditional feline queening calendar window from actual mating and independently veterinarian established applicable earliest/latest intervals. Mating not fertilization, date uncertainty retained; no guaranteed birth date, pregnancy confirmation or permission to delay care.
Description
Queening dates measured from mating retain uncertainty about the biological timing of pregnancy.
Queening dates measured from mating retain uncertainty about the biological timing of pregnancy.1
A veterinarian-established interval supplies a conditional feline birth window rather than confirmation of pregnancy.
When to use Queening Date From Mating Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Establish the animal, measurement protocol, units and independently applicable veterinary prescription or reference.
How to use Queening Date From Mating Calculator and understand its results
- Establish the animal, measurement protocol, units and independently applicable veterinary prescription or reference.
- Enter actualRecordedMatingDate, callerVeterinarianEstablishedEarliestMatingToBirthDays, callerVeterinarianEstablishedLatestMatingToBirthDays, using the field meanings and rules below, then run the tool.
- Read result.conditionalCallerEarliestBirthDate, result.conditionalCallerLatestBirthDate. Use the units and subtraction order below to interpret each value; retain negative differences where returned.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualRecordedMatingDate | Actual recorded mating date | string | Required |
| callerVeterinarianEstablishedEarliestMatingToBirthDays | Caller veterinarian established earliest mating to birth days | number | Required |
| callerVeterinarianEstablishedLatestMatingToBirthDays | Caller veterinarian established latest mating to birth days | number | Required |
Enter the recorded mating date as a real Gregorian YYYY-MM-DD in years 0001..9999. Supply veterinarian-established earliest and latest offsets as integers: 1≤earliest≤latest≤500. Shift the mating date by each offset using calendar-day arithmetic. A result outside years 0001..9999 fails; time zones and time of day are not modeled.
earliestDate=matingDate+earliestDays; latestDate=matingDate+latestDays Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Qualified observation, conditional calculation or reference | object |
| result.conditionalCallerEarliestBirthDate | Recorded mating date plus the supplied earliest interval. | string |
| result.conditionalCallerLatestBirthDate | Recorded mating date plus the supplied latest interval. | string |

}Limitations and assumptions
The patient context, observations and applicability of any reference or prescription must be independently established. This result supplies no diagnosis, default dose, treatment selection or assessment of clinical suitability.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use Whelping Date From Mating Calculator: Whelping dates measured from mating have uncertainty because the recorded mating date is not necessarily the fertilization date. For a complementary comparison, use Dog Gestation Age From Ultrasound Calculator: Canine ultrasound measurements can be compared with an applicable dimension-to-gestational-age calibration.
