Cadence and interval are close enough that they can seem redundant, but one is a measurement and the other carries a claim about intention.
Choose "cadence" when the point is the broader operating practice or system that recurrence supports; choose "interval" when the point is simply the amount of time between events -- interval names the gap, cadence names the practice.
A narrower, more technical word
"Interval" is a narrower, more technical word: it just measures the time between two occurrences. It doesn't claim anything about whether the recurrence is a deliberately maintained practice -- it's a pure measurement, closer in spirit to a stopwatch reading than to a description of how a team works.
Interval (measurement): "The interval between releases is fourteen days."
That sentence states a fact about timing and nothing more -- it doesn't claim the team designed this on purpose, or that they're actively sustaining it as a practice worth naming.
Cadence carries the intent alongside the measurement
"Cadence" carries more -- the sense that the recurrence is a deliberate, ongoing practice worth naming, maintaining, and adjusting.
Cadence (practice): "Our biweekly design-review cadence gives the team a predictable rhythm to plan around."
Here the sentence is doing more than reporting a number -- it's naming an established practice that the team relies on and could choose to revisit.

Both natural, different focus: "We shortened the interval to one week, which changed our whole release cadence."
This sentence uses both words precisely: interval names the specific number that changed (from whatever it was to one week), and cadence names the broader practice that number is part of. Neither word could substitute for the other here without losing precision.
The mistake to avoid
The mistake is treating "interval" as a full substitute for "cadence" -- interval names the gap between events; cadence names the practice built around that gap, including the intent to maintain it. If a sentence is purely about a number -- how much time passes between two points -- interval is the more precise, more technical choice. If the sentence is about a practice a team owns, maintains, and could change, cadence carries the fuller meaning interval alone doesn't.
Interval as the building block, cadence as the finished practice
One useful way to hold these apart: interval is the raw material, and cadence is what a team builds out of it once the interval becomes an agreed, maintained way of working. A fourteen-day interval is just a number until a team actually commits to shipping on it repeatedly -- at which point it becomes a release cadence. The number doesn't change when that happens, but the sentence needs a different word to reflect that something more than a measurement now exists.
Where the two overlap comfortably
In practice, the two words often appear close together without any tension, because they're answering related but distinct questions in the same conversation. A planning document might state the interval precisely ("fourteen days") while using cadence to describe the broader practice built on top of it ("our release cadence has held steady at that interval for two quarters"). Neither word is doing the other's job in that sentence -- they're working together, each contributing exactly what the other can't.
Practice scenarios
Practice using cadence in situations like:
- choosing between a pure time measurement (interval) and a maintained practice (cadence)
- using both words in one sentence to name a specific change and its broader effect
- catching "interval" used where the sentence actually needs the fuller claim cadence carries
Useful practice phrases:
- "The interval between releases is fourteen days."
- "Our biweekly design-review cadence gives the team a predictable rhythm."
- "We shortened the interval, which changed our whole release cadence."
Interval measures the gap; cadence names the practice built around it.
When a sentence is really about ownership and intention, not just a number, cadence is the word that carries the fuller claim.
