6AM, the first hour of the day on a Sunday, belongs to Sun. The Sun's hours were kept for success, vitality and public standing: audiences with the powerful, matters of honor and reputation, healing directed at the heart and the vital spirit, and any operation meant to draw favorable notice. The grimoire tradition reads the Sun as the most fortunate of the seven when the operation suits its light. Practitioners were counseled to match the work to the hour wherever the two could be arranged together, choosing an hour whose ruling planet suited the operation in hand rather than acting in whatever hour happened to be free; a working that fit its planet well was held to draw strength from the hour, while one that fought the ruling planet's nature was held to labor against it.
Because the same planet returns roughly every seventh hour through the whole day, Sun also rules 3AM, 1PM and 8PM elsewhere on this reference Sunday, so a practitioner without access to 6AM specifically could look to those instead for work of the same character. The hour sits inside a wider correspondence system built around the same seven planets: Sun is paired with the metal gold, with gold or yellow, and with Sunday, the weekday carrying its name in full as well as its first hour. A working timed to 6AM was traditionally strengthened further by choosing Sunday itself and by using that metal and color in the object the working required, and the same logic timed ordinary practical acts as well as ritual, from gathering herbs held sacred to a planet to medical treatments believed to answer best to its temperament.
