Minute Repeater Chime Sequence Calculator

Construct ordered low/high minute-repeater chime sequence and group boundaries using caller nominal gong frequencies; differs from strike count, assumes hour lows then high-low quarters then minute highs, not generated audio or actual acoustic timing.

Description

A minute-repeater sequence can distinguish hour, quarter and residual-minute groups.

A minute-repeater sequence can distinguish hour, quarter and residual-minute groups. Gong frequency labels do not establish real acoustic timing.^[1]

Enter integer hour 0–23/minute 0–59 and positive low/high gong frequencies with high>low. Return ordered labels/frequencies and exclusive group-end strike indices.

When to use Minute Repeater Chime Sequence Calculator

Use Minute Repeater Chime Sequence Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. Midnight/noon uses 12 hour strikes. No audio, actual delays or universal movement convention is generated.

Prepare the measured watch or gearing records and verified movement specifications requested. Confirm tooth counts, quarter-hour ordering and caller strike conventions.

How to use Minute Repeater Chime Sequence Calculator and understand its results

Prepare the measured watch or gearing records and verified movement specifications requested. Confirm tooth counts, quarter-hour ordering and caller strike conventions.
Enter observedHour24, observedMinute, callerLowGongFrequencyHz, callerHighGongFrequencyHz using the field table and calculation rules, then run the tool.
Read orderedGongLabels, orderedNominalGongFrequenciesHz, hourGroupEndExclusiveStrikeIndex, quarterGroupEndExclusiveStrikeIndex. 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
observedHour24	Observed hour24	number	Required
observedMinute	Observed minute	number	Required
callerLowGongFrequencyHz	Caller low gong frequency hz	number	Required
callerHighGongFrequencyHz	Caller high gong frequency hz	number	Required

Enter integer hour 0–23/minute 0–59 and positive low/high gong frequencies with high>low. Return ordered labels/frequencies and exclusive group-end strike indices.

sequence=hour12 lows, quarterCount high-low pairs, residualMinute highs

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
orderedGongLabels	Ordered gong labels	list of string
orderedNominalGongFrequenciesHz	Ordered nominal gong frequencies hz	list of number
hourGroupEndExclusiveStrikeIndex	Hour group end exclusive strike index	number
quarterGroupEndExclusiveStrikeIndex	Quarter group end exclusive strike index	number

Limitations and assumptions

Midnight/noon uses 12 hour strikes. No audio, actual delays or universal movement convention is generated.

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 Petite Sonnerie Strikes Per Day Calculator: Petite sonnerie can strike hours at exact-hour slots and quarters between them. The enabled schedule defines the modeled day. For a complementary task, use Grand Sonnerie Strikes Per Day Calculator: Grand sonnerie can repeat hour strikes at each enabled quarter slot. Quarter chimes and hour chimes contribute separate hammer counts.
