Day mapping

Each of the seven days in a week have three bytes within the 21-byte timebox value. These bytes are in chronological order from most-significant byte to least-significant byte. (Note that this is the opposite of chronological bit order within each byte, which is LSB to MSB.) The starting point of a week is 4 PM on Saturday afternoon.

The table below shows how each day’s three bytes (0-2) map to the timebox value’s bytes, listed here in order from most-significant byte to least-significant byte.
