Wrong date in Firefox on October

[riotera]

On October 2015 the calendar repeats the day 17th instead of 18th. It happens on the demo in the official site too

On iPad the first Sunday in October get Saturdays date. Fine on Firefox on PC

In attachment what I see in Firefox on Mac (17th twice)

Happening again in 2016, now duplicating the 15th day. The date-pick attribute seems correct (time) but not the formatted date.

Hey @riotera. Thanks for your support.

I am from Brazil, UTC-3. The problem just happens in the month October each year and here we exited the Daylight Saving Time in 19, February.

[riotera]

Yes but will enter in 15th October 2017

@riotera When I select the 15th October 2017 (Sunday), is salve one day before: 14th October 2017

For me the problem is repeated in all October months (using Firefox Browser).

I thinks this is a old bug: #180
