schedule
📅 日 (day) + 程 (procedure/journey) = the plan laid out day by day: a schedule
日 means day; 程 means procedure or stage of a journey. Together they form the run of days you have mapped out — your schedule or itinerary. Note 程 chéng rhymes with the chéng in 工程 (engineering): a structured process.
日 — pictograph of the sun
日 is a pictograph of the sun, originally drawn as a circle with a dot or stroke inside representing the sun's substance. Over time the round shape was squared off into the modern rectangular form. It means 'sun' and by extension 'day'.
