GPU and RAM supply doesn't change over the course of one weekend usually though. So there would have been no reason not to wait until Monday or do it before Saturday.
I don't think that the day of the week matters that much. But the correct way to rise prices is clearly:
- announce the new prices and the day from which on they are valid.
- ensure that your customers have time to react based on your announcement.
Based on the article it seems like the only information before the change was "some day in january we will change prices" which would not be enough for me as a customer...
They've got the analytics. The correct answer is the time of week the most customers are paying attention to their pricing and services, which probably falls within the standard 9-5 work week.
Give customers time to react and plan, so announced at least a couple weeks ahead of time.
I always found that idea funny. For most people the most important thing over the course is working days and time off days. When do they have to get up, when do they have to work, when do they need to get going early, to get to some work location, an office maybe, and when do they not have to work. Saying that "the week starts on Sunday" makes me immediately think: "Oh, you start working on Sunday?". In most people's minds in my bubble the work starts on Monday, which makes it the more natural start of the week, at least I would argue. To me personally starting the week on Sunday seems removed from most people's job and work reality.
In many calendar applications one can actually configure things like that. Often the option is directly named something like "start week on Monday/Sunday".
We also shouldn't neglect the fact, that other cultures other customs. Maybe the week starts on Sunday in your location, maybe it doesn't in my location.
