# When do fuel stations change their prices in Slovenia?

Window: Jun 24, 2026 – Sep 21, 2026 · 90 days · rebuilt every night

- A station in Slovenia changes its 95 petrol price 0.95 times a week on average, and a price that has just changed then holds for 7 days before the next one.
- On an ordinary day 0.0% of the stations in Slovenia change their price; on the busiest day of the window, 96.6%.
- The busiest weekday is Tuesday, with 86.7% of all changes; the quietest is Monday, with 0.0%.
- An increase moves the price by 0.042 EUR/L on average, a cut by 0.059 EUR/L. Over the window there were 2 770 changes upward and 690 downward.
- Half of all the price changes of the last 48 days happened on just 4 of them.
- When M – ENERGIJA moves, 100% of its own stations move on the same day — the price of a station in this network is not set at the station.
- Petrol reaches the centre of a market-wide move first in 6 of the 6 waves we measured; the rest follow at a median of 0.0 days.
- Across the window the market median went from 1.583 EUR/L to 1.728 EUR/L.

## How this was measured

One price per station per day. The daily history table holds one row per station, fuel and day. A row is also written back to the date the source itself gives as the moment of the change, so a change lands on the day the operator made it, not on the day we happened to read it.
A change is two consecutive days in a station’s series with different prices; it is counted on the second of the two. If more than 3 days separate the two readings, the pair is dropped — there is no way to say which day the price moved.
A market-wide move — a “wave” — is a run of days on which at least 48% of the stations with a price changed it; the threshold is not a fixed number but the market’s own median plus half the way to its 95th percentile. Within a wave each network gets the centre of gravity of its own changes; the network whose centre falls earliest moved first. Waves found in this window: 6.
The figures are rebuilt once a night from the full history, not on every visit.

## What this cannot tell you

At most one change per station per day is visible, because the history keeps one price per station per day. A station that changes twice in one day is counted once.
It cannot be established for Slovenia. Our history keeps one price per station per day, so we know the day a price changed but not the hour. Nothing on this page claims otherwise.
