On Nova, “Today” is the current day in your marketplace’s time zone. Not your computer’s clock, not UTC. For a seller on Amazon.com, Today starts and ends at midnight in Los Angeles, because that is the clock Amazon itself uses to count your day.

Amazon does not count an order on the day it happened where you live. It counts it on the day it happened on the marketplace. For Amazon.com and Amazon.ca that clock is Pacific Time: Seller Central’s Business Reports and Sales Dashboard are cut at midnight Pacific, whatever your own time zone, and Amazon offers no setting to change it. For the European marketplaces Nova uses the Central European day, and every other marketplace keeps its own local day.

Nova counts your days on the same clock, on purpose. A day on Nova is the same day as on Seller Central, order for order. When you check a figure on Nova against your Business Reports, the two days line up. If Nova cut days at midnight in Paris or in New York, they never would.

You sell on Amazon.com and you live in New York. It is 9 pm on September 1. In Los Angeles it is 6 pm: the Amazon day of September 1 still has six hours to go, and orders are still coming in. Nova’s Today tile says September 1 and keeps filling up until 3 am your time, when the Pacific day ends.

A dashboard that cut days in UTC would already say September 2 at 8 pm New York time, with nothing in it: no order exists on that day yet. That is why Nova never uses UTC for your days.

Today flips at midnight on the marketplace. Seen from where you are:

Until it flips, the Today tile shows the day in progress. Nova refreshes it through the day, so a figure you read at noon will grow by the evening. Yesterday becomes complete once the marketplace day has ended and Amazon has finished reporting it.

Each marketplace keeps its own day: a French order placed at 00:30 in Paris belongs to the new French day, while an American order placed at the same instant, 3:30 pm in Los Angeles, still belongs to the previous American day. Nova never moves an order from one day to another.

What Nova does need is one clock to say when “Today” starts on the dashboard. By default it takes the westernmost of your marketplaces, the day every marketplace has begun. For a workspace on Amazon.com and Amazon.fr, that is Pacific Time.

In practice, for a seller in Paris with both: between midnight and 9 am, the Today tile still shows the previous day, with American orders still coming in and the French day complete. At 9 am it flips, and the French orders placed since midnight appear under the new day, where they always were. Nothing is lost or moved; only the moment the tile turns the page changes.

If you would rather have Today flip on another of your marketplaces’ clocks, an organization owner can choose it in Settings › Workspaces › Reporting day. The choice is offered only when your marketplaces span several time zones, it applies to every member of the workspace, and it changes when Today flips, never the figures of a day.

Does Nova use my computer’s time zone? No. Two people looking at the same workspace from different countries see the same Today, and it is Amazon’s.

Why not UTC, like many tools? Because no Amazon figure lives on a UTC day. UTC midnight is 5 pm in Los Angeles: a UTC dashboard would show an empty “tomorrow” every evening for American sellers, and would never match Seller Central.

My Today figures are lower than what I see on Seller Central right now. Today is a day in progress on both sides. Compare a finished day, or wait for Nova’s next refresh.
