Ok, I'm about to drop the actual timeline of events from the drama below for those who still wonder how much time has passed between the different parts of the story.
The makers actually bothered creating proper docs and putting up correct dates on them all, so apparently they wanted the viewers to follow.
Spoiler below, don't read ahead if you haven't watched it yet.
The drama starts with HT's return to China. This happens in the second week of November 2022. This can be guessed from JX's calendar and the date on the doctor's report presented during the first meeting on Xiao Bay the robot, where HT and JX first meet
10.11.22 - HT and JX meet for the first time after college, first the accident, then at the meeting (date is much later shown when HT buys lottery tickets)
22.11.22 - HT and JX meet at the village (date is on the schedule that HT sees JX's name on and plans to go too)
29.11.22 - Xingchen is registered (date on business license and the message TS shows HT)
14.12.22 - SYC & JX's 4th anniversary, day of the play, HT finds out she has a boyfriend, SYC proposes JX (date on play tickets)
21.12.22 - HT & JX sign contract, she wears the ring and is officially engaged (date on contract)
22.12.22 - XC receives first round of investment money (date on their account info)
23.12.22 - SYC breaks up with JX, JX and HT meet at the event, she gets drunk later (date on event invite)

Germany
01.11.23 - the volunteer's operation (date on the investigation report later made on the case)
03.11.23 - JX's birthday and the subsequent events (HT's passcode tells JX's DoB is 03.11.95)
25.11.23 - HT's birthday, aquarium visit (HT's birthday 25.11.94 is mentioned on the guest information when he delivers the speech)
The star gift certificate also has this date and maybe it was meant to be a birthday gift, but they seemed to have moved that scene a few days before.

03.12.23 - SYC and WQZ's wedding, next day the girl in the office calls SZZ at night for help to retrieve a report she was working on, and then confesses (date 4.12.23 is on the report)
10.12.23 - Heated exchange between HT and JX (and break up), deal between DongYang and TongKe ( date on their contract)
11.12.23 - merger, JX resigns from HanHai-XingChen (date on resignation letter)
08.09.24 - HT and JX accidentally meet in Munich after months of separation, next day they travel back to China together (date 09.09 on HT's boarding pass)
