Mileage & Time Intervals

A maintenance interval can be tracked by mileage, by time, or by both at once. When both are set, the service is due whenever the first threshold is reached — whichever comes first.

Creating an Interval

When you create an interval, fill in the frequency for the dimension(s) you want to track:

• Frequency (km) — track by distance, e.g. every 10,000 km
• Frequency (days) — track by time, e.g. every 365 days
• Both — fill in both fields to track mileage and time together

There’s no interval type to choose. The type follows whichever frequencies you fill in:

• Mileage only → tracked by distance
• Time only → tracked by time
• Both → whichever comes first

You can also set an advance notice for each dimension (e.g. 500 km or 30 days) to be warned before the service is actually due.

Whichever Comes First

With both a mileage and a time frequency set, the interval becomes due as soon as either threshold is reached. In the overview, the progress and status reflect the dimension that’s driving it — for example, an oil change set to 10,000 km or 12 months will show as overdue on the date even if there are still kilometres to go.

The Same Date Every Year

Some work is due on a calendar date, not a number of days after it was last done — winter tyres by 10 November, summer tyres by 1 April. Counting 365 days from the last change would drift: fit the tyres three weeks early one year and the next reminder comes three weeks early too.

For work like this, switch the time schedule from Days since last service to Same date every year and pick the day and month.

• Advance notice works as usual. With 30 days, the interval shows as due soon from 11 October and as overdue from 10 November.
• Recording the service moves the interval to next year’s date, whether the work was done early or late. A service counts for the yearly date it is closest to.
• A new assignment is first due on the first such date on or after its tracking start date. Pick an earlier start date if the vehicle is already behind.

A yearly date can be combined with a mileage frequency, and the service is then due whichever comes first.

Assigning to Many Vehicles

Open the interval and use the Available list on the right:

• Assign all assigns every vehicle in the list. Search first to narrow it — by name, plate, brand, model or class — and the button assigns only what the search shows.
• Tick individual vehicles and the button becomes Assign selected.

All of them share one tracking start date. Mileage tracking starts from each vehicle’s own current odometer reading. Vehicles that already have the interval are skipped.

Updating an Existing Interval

You don’t need to recreate an interval to change how it’s tracked:

1. Open the interval from the Intervals tab.
2. Add or change a frequency — for example, enter a days frequency on an interval that was previously mileage-only.
3. Save.

The type updates automatically based on the fields that are filled in. So a mileage-only interval becomes mileage + time the moment you add a time frequency.

To stop tracking a dimension, clear its frequency field and save. At least one of a mileage frequency, a frequency in days or a yearly date must always be set.
