I went to https://gov.immigration1.queueonline.net/appointment/login.html?v28 to make an appointment for extension based on retirement. The system shows Booking period: Nov 23, 2024 - Dec. 22, 2024 (FULL). But I can't seem to move the calendar from November to December or January to choose another date. My extensions expires Feb. so I have time. But shouldn't I be able to make an appointment for late Dec. or Jan. now? I know that I can go in 45 days before.
