+// Submit Logic:
+// * ✅ Value:
+//    * merged value using controlled value, if not, use stateValue
+//    * When merged value change, [1] resync calendar value and submit value
+// * ✅ Calender Value:
+//    * 💻 When user typing is validate, change the calendar value
+//    * 🌅 When user click on the panel, change the calendar value
+// * Submit Value:
+//    * 💻 When user blur the input, flush calendar value to submit value
+//    * 🌅 When user click on the panel is no needConfirm, flush calendar value to submit value
+//    * 🌅 When user click on the panel is needConfirm and click OK, flush calendar value to submit value
+// * Blur logic & close logic:
+//    * ✅ For value, always try flush submit
+//    * ✅ If `needConfirm`, reset as [1]
+//    * Else (`!needConfirm`)
+//      * If has another index field, active another index
+// * ✅ Flush submit:
+//    * If all the start & end field is confirmed or all blur or panel closed
+//    * Update `needSubmit` mark to true
+//    * trigger onChange by `needSubmit` and update stateValue
