Since I got a pretty good reception from Comp authors to using Euphoria (a web-based chat app that is friendly to casual and open discussions), I’m organising a chat/discussion about how IFComp went, both to talk about the games themselves and to talk about organisational/community things.
Surely, if there it at least one hour’s difference between timezones, it is quite possible for it to be the 20th AND saturday at the same time in different places.
(couldn’t resist! Sorry!)
EDIT - In the English calendar, the week days go like MTWTFSS. In Portuguese/Brazilian they go STQQSSD. It gets really easy to confuse wednesday/thursday, and friday/saturday. FWIW. I do it all the time.
OK. Now I’m confused again. Friday 20th, which is the time showing in this countdown timer thing, I can’t do. Saturday 21st I can. I didn’t see Sequitur clarify the timing before the timer was put up. I’m not fussed either way (save to the extent that I would rather like to participate), but I still don’t think it’s clear. The problem was frankly nothing to do with time zones, and everything to do with the 20th not being a Saturday in Portugal, Greenwich, Australia or any other part of the world.
I’ve now updated the time zone and countdown timer to show both alternatives, i.e. Friday the 20th and Saturday the 21th.
And of course, you’re right, the 20th is a Friday in any part of the world. The day of the week a given date falls on does not depend on which time zone you’re in. (On the other hand, for a given moment in time, the current date (and thus the day of the week) can have up to3 different values, in different parts of the world.)
So while the date ‘20th of November 2015’ is always a Friday, the time ‘4 PM on the 20th of November EST’ may be either a Friday or a Saturday, depending on where in the world you are at that time.
