A market holiday call via Websocket API has a returning response with holiday dates for current year. When will the API switch to returning data for next year and what timezone should I refer to?
E.g. I need to schedule a job that somehow gets the proper holiday dates for next year: Can I schedule it before 1st of Jan? If not, can I schedule it on the 1st of Jan at 1 AM (GMT +2 or 3) and assume it will return expected data?
