Days on Market and Price History: Consumer Information and Limits
The days-on-market number and the price history chart are two of the most-read facts on any listing page, and two of the most misunderstood. Here is how they are actually counted, who defines them, and what they can and cannot tell a consumer.

The direct answer
Days on market and price history are defined and displayed differently by each system, and the numbers consumers see are not always the underlying record. ARMLS tracks both an agent-level and a cumulative days-on-market counter that only reset through a defined off-market relisting period, consumer portals like Zillow run their own counters with their own reset thresholds, and price history is assembled from public records and MLS data. Consumers can use these as limited signals about exposure and price movement, provided the definition of each number is attached to it.
Key takeaways
- Days on market is displayed differently from how it accumulates: ARMLS separately tracks Agent Days on Market (ADOM) and Cumulative Days on Market (CDOM), and portals like Zillow run their own counters, so the number a buyer sees can differ from the underlying listing history.
- Under current ARMLS rules, neither ADOM nor CDOM resets from a price change or a listing edit; the only reset is keeping a listing off-market (Cancelled or Expired) for more than 45 consecutive days and relisting on or after the 46th day.
- On Zillow, the days-listed counter resets only when a home has been off-market for more than 31 consecutive days; relisting with a new MLS number does not, by itself, reset Zillow's counter.
- Price history on consumer portals is assembled from public records and MLS listing data, so it may include tax records, list-price changes, and sale prices, with coverage that varies by market and platform.
- Consumers use days on market and price history as signals about exposure, competition, and price trajectory, and those signals have real limits: they are historical records, not explanations of intent, and reading them requires the platform's definitions attached.
How does ARMLS actually count days on market?
ARMLS maintains two counters. Agent Days on Market (ADOM) counts the days the property has been listed with an individual agent, accruing from the list date. Cumulative Days on Market (CDOM) counts the days the listing has been live in ARMLS's system since it first went live. Both counters accrue only while a listing is in an active status, and both stop accruing when the listing closes, cancels, expires, goes pending, sits in coming-soon, or is temporarily off-market.
The only reset under ARMLS rules is time off-market: a listing must stay cancelled or expired for more than 45 consecutive days, and relisting on or after the 46th day starts both counters at zero. The 45-day rule replaced an earlier 90-day requirement in June 2020, which is a reminder that these rules change and are set by the MLS, not by any individual brokerage.
The ARMLS days on market page and its reset explanation are the documented authority for the current rules.
How do consumer portals display their own counters?
Zillow's days-listed counter tracks how long a home has been actively listed on Zillow and resets only when the home has been off-market for more than 31 consecutive days. A relist through the MLS with a new listing number does not reset Zillow's counter by itself, and editing photos or changing the price does not reset it either. Zillow's own support documentation sets out those rules, and the mechanics of other portals' counters vary; this guide records the definitions that are documented rather than asserting rules for platforms that do not publish them.
The practical consequence: the same home can show a different days-on-market figure on the MLS, on Zillow, and elsewhere, because the definitions genuinely differ. A consumer comparing listings should read the number together with the source and the definition, not as one universal truth.
What is a price history, and where does it come from?
A price history is a record of price-related facts about a property: prior list prices, sale prices, and often tax or assessment records. Consumer portals assemble it from public records and the MLS listing data, and the coverage varies by market, county, and platform. It is a factual trail of what was recorded, not an explanation of why prices moved.
Consumers can use it well: spot a pattern of list-price reductions, compare a current price to prior sale prices, and prepare questions for the seller's disclosure and the listing agent. The limit is equally real: a price history cannot tell you a seller's motivation, a buyer's circumstances, or the condition of the home at the time of a prior sale, all of which shape list prices.
What can consumers honestly read from these signals?
- Days on market is a proxy for exposure and competition, with definitions attached.
- A reset reflects the listing process (off-market time and relisting), not a home's actual history.
- Price history shows recorded facts; it does not explain intent or predict the future.
- Cross-check any number against the source: the MLS, the portal's help page, or the county recorder.
This guide makes no claim that resets are fraud, that brokerages benefit uniformly from any practice, or that information is being suppressed anywhere. The rules and definitions are what they are, and they belong to the systems that publish them.
How should a seller think about their own listing's numbers?
Sellers see days on market and price history through the same limited lens: they are records, not verdicts. A long days-on-market can reflect pricing, condition, or a slow segment; a reset can reflect a deliberate off-market strategy. The useful work is reading the number alongside the evidence, which is exactly what a strategy conversation around positioning, pricing, and market feedback is for.
No one can promise a home will be given a fresh appearance on consumer platforms by relisting, and practices that mimic reset conditions should be evaluated for whether they serve the seller's real goal, not for the cosmetic effect alone.
Frequently asked questions
Does a price reduction reset days on market?
Not under current ARMLS rules: a price drop or any listing edit does not reset ADOM or CDOM, which keep accruing while the listing is active. On Zillow, editing photos or changing the price also does not reset the days-listed counter. A reset generally requires the listing to come off-market for the required period and come back as a new listing.
Why does days on market look different on different sites?
Because the platforms define it differently. ARMLS uses ADOM and CDOM with its own accrual and reset rules, and consumer portals like Zillow maintain their own counters with their own off-market thresholds. The same home can legitimately show different days on market across sources, which is why the definition belongs next to the number.
Can a seller legally get their days on market reset?
Under ARMLS's published rules, a listing that stays off-market (Cancelled or Expired) for more than 45 consecutive days can relist as a new listing with both counters reset to zero, with the relisting allowed on or after the 46th day. Whether that is a sensible strategy is a separate question from whether it is permitted, and the MLS rules, not any individual's preference, decide it.
What can price history tell me about a home?
Price history records what the listing data and public records show: prior list prices, sale prices, and sometimes tax records. It is a factual trail, not an explanation of why prices changed. Use it to spot patterns and ask questions; do not use it to assume a seller's motivation or the trajectory of a market.

Reading your listing's numbers the honest way?
Days on market, price history, and listing feedback only make sense with the definitions and the market attached. A strategy call reads your home's numbers against the evidence and builds the response.
