Can You Use Your Calendar as a Mileage Log?

What your calendar has

If you use Google Calendar or Outlook for work, your calendar already contains:

• Dates and times of every appointment
• Locations (if you fill in the location field)
• Business purposes (in the event titles)

What your calendar is missing

Your calendar does not calculate driving distances between appointments. It does not apply HMRC mileage rates. And it does not produce a compliant report for your Self Assessment.

So while your calendar has most of the data, it is not a mileage log on its own. It is a source of data that can be turned into a mileage log — with the right tool.

How MileageCalendar fills the gap

MileageCalendar connects to your calendar and reads the locations from your appointments. It then calculates the driving distance from one appointment to the next, applies the HMRC mileage rate, and creates a draft mileage entry.

Your appointment title becomes the business purpose. The date is taken from the event. The start and destination are taken from the locations. The distance is calculated automatically. The only thing you do is review and confirm.

So can you use your calendar as a mileage log?

Not directly — but with MileageCalendar, your calendar becomes the source of your mileage log. You do not need to maintain a separate record; the calendar does the work, and MileageCalendar turns it into compliant mileage records.

This is the most efficient approach for anyone who already uses a calendar for work. No double entry, no forgotten journeys, no manual distance calculations.
