How to tag opening hours when location is open every other week

Help and support

There’s a location in my area where they are open every other Friday.

I would like to tag this correctly in OSM, but the closest thing I could find would be setting the business to be open on certain weeks of the month.

Is it possible to tag opening hours in this way?

I think something like week 01-52/2 Fr 09:00-17:00; PH off might do it. Changing the start week to 2 would offset the result by a week (at least the way that checker interprets it).

Based on somewhat cryptic explanation here. This might not continue correctly at the start of the next year.
