延期了吗：工期日历

Have you also encountered the situation of renovation companies delaying the renovation? Are you still counting the number of working days that have passed on the calendar, whether there is a delay, how many working days are left, and how many days have been delayed?
When I was renovating before, because the rest time of the renovation workers was different from the legal holidays, the Spring Festival holiday was particularly long, and there were also some special holidays such as the third day of the third lunar month in Guangxi which was a holiday. Then for the 75 working days agreed upon for the renovation, it was very inconvenient to count by myself looking at the calendar, and I had to exclude various rest days. Moreover, there was no intuitive data dashboard that could show how many days were left each day. So I made such an app.
Core functions:
1. Provide a construction period calendar: Mark each date on the calendar as the nth working day of the project, automatically synchronize the holidays announced by the State Council, and you can customize to change working days to rest days or rest days to working days. For example, with agreement, certain dates can be marked as rest days and not counted into the construction period.
2. Automatically calculate the remaining working days, estimated deadline, and how many days have been delayed
3. You can add notes under the date for convenient review through the timeline later.
4. You can export a long picture of the construction period calendar for use when communicating with the contract party.
The data is stored locally and simultaneously synced to iCloud as a backup to ensure data is not lost, and it also supports use on multiple devices (such as iPhone + iPad).
The backup data is stored in iCloud with privacy protection.
Since the APP needs to obtain holiday data and back up data to iCloud, it will apply for network access permissions.
