15 hour shift

how often can i be on duty for 15 hours?

6 days a week with the right amount of break

or if you dont get a split day in then three times a week

As long as you have the required breaks you can do a 15 hour spread-over 3 times between weekly rest periods.
If you have split daily rest periods you can do a 15 hour spread-over every working day but of course that wouldn’t really be duty time as you mentioned.

I think you would also have to bear in mind the average 48 hour week under the WTD - it would depend on how much time was driving & other work as rest, breaks & POA do not count for the WTD.
