Here is a very minor poinr. To me '2015 Apr Jul Oct' as in https://analytics-prototype.wmflabs.org/#/contributing works better than 'D J F M A M J J A S O N D'.as on the dashboard. Even month numbers would work better. Maybe this is a matter of taste.though.

I agree AMJJASOND is likely to be confusing to anyone but the most astute English speakers. Hm... maybe roman numerals so it stands apart from the other numbers on the chart? Problem is there's not a lot of space under those charts.
Roman numerals are really, really horrible and non-intuitive!
Yeah, hard problem then... How about localized month abbreviations? Vertical text?
Either localised abbreviations or month numbers, I think
