Moonrise Delay Minutes Per Day
Actual consecutive lunar-rise timestamp offsets from 24 hours, signed delays retained; caller confirms consecutive events, not universal 50 minutes per day. Model only, not an ephemeris, measured stellar identity or observational guarantee.
Description
Successive moonrise timestamps can be compared with one ordinary solar day.
Successive moonrise timestamps can be compared with one ordinary solar day.1
Their delays depend on actual events and do not establish a universal daily rise interval. Use Moonrise Delay Minutes Per Day to evaluate the supplied inputs under the model explained below.
When to use Moonrise Delay Minutes Per Day
Use Moonrise Delay Minutes Per Day to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Moonrise Delay Minutes Per Day and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Observed moonrise utc times using the field table and validation rules below, then run the tool.
- Read Observed daily rise delay minutes, Observed mean rise delay minutes; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedMoonriseUtcTimes | Observed moonrise utc times | array of string | Required; constraints below |
Enter at least two actual successive-day moonrise timestamps in exact YYYY-MM-DDTHH:mm:ssZ notation, strictly increasing and real Gregorian UTC dates. For each adjacent pair divide elapsed milliseconds by 60000 and subtract 1440. Return delays and their arithmetic mean in minutes. Seconds are required, offsets and fractional seconds are rejected. The tool does not verify that supplied events belong to consecutive dates or compute a rise event.
delayMinutes[i]=elapsedMinutes(event[i],event[i+1])−1440; mean=arithmeticMean(delays) Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| observedDailyRiseDelayMinutes | Observed daily rise delay minutes | array of number |
| observedMeanRiseDelayMinutes | Observed mean rise delay minutes | number |

}Limitations and assumptions
Their delays depend on actual events and do not establish a universal daily rise interval. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
