Minute Repeater Strike Count
Count hammer strikes for a two-gong minute repeater: hours, paired quarter-hour strikes, then minutes since the quarter.
Description
A two-gong minute repeater sounds hours, paired quarter strikes and remaining minutes.
A two-gong minute repeater sounds hours, paired quarter strikes and remaining minutes. Each quarter contributes two hammer strikes.1
Count hammer strikes for a two-gong minute repeater: hours, paired quarter-hour strikes, then minutes since the quarter.
When to use Minute Repeater Strike Count
Use this tool to count hammer strikes for a two-gong minute repeater: hours, paired quarter-hour strikes, then minutes since the quarter.
Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.
How to use Minute Repeater Strike Count and understand its results
- Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.
- Enter hour, minute using the field table and calculation rules, then run the tool.
- Read hourStrikes, minuteStrikes, quarterStrikePairs, totalStrikes. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| hour | Hour on 12-hour dial | integer; minimum: 1; maximum: 12 | Required |
| minute | Minute | integer; minimum: 0; maximum: 59 | Required |
Enter integer hour 1–12 and minute 0–59. Return hour strikes, quarter pairs, minute strikes and total.
quarters=floor(minute/15); total=hour+2quarters+minute%15 Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| hourStrikes | Low-gong hour strikes | integer; minimum: 1; maximum: 12 |
| minuteStrikes | High-gong minute strikes | integer; minimum: 0; maximum: 14 |
| quarterStrikePairs | High-low quarter pairs | integer; minimum: 0; maximum: 3 |
| totalStrikes | Total hammer strikes | integer; minimum: 1; maximum: 32 |

}Limitations and assumptions
No clock time is read or mechanism operated. Quarter pairs are not individual strikes.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Escapement Impulse Rate: Compare detent, duplex, and natural-escapement impulse rates from the balance beat rate without conflating beat and full oscillation. For a complementary task, use Accessible Watch Time Output Mode Lookup: Return an audio, haptic, tactile, inclusive-design, or terminology fact for accessible watch time output instead of inventing audible hands.
