I've got a food menu which needs to have a pattern for when certain menus are displayed on a website.
我有一个食物菜单,需要有一个模式,以便在网站上显示某些菜单。
For example, the pattern is split into yearly quarters, weeks and days.

**Quarter 1**
**Week 1**

Tuesday: 4
Wednesday: 5
Thursday: 4
Friday: 6
Saturday: 7
Sunday: 7
The numbers represent the ID of the menu in the database.
