You may consider it somewhat silly to have a recipe for determining the quarter of a date since quarter is included in the default hierarchy for a date. However, many organizations do not adhere to a standard calendar quarter. For example, Microsoft's fiscal calendar runs from June to May. Other organizations start and stop their quarters on specific dates of the year. This quarter calculation can be used with standard quarterly calendars as well as non-standard quarterly calendars. It is easily modified to fit just about any custom quarterly schedule you can imagine. The quarter table that we will create in this recipe has the following quarters:
- Q1: August 15 – November 14
- Q2: November 15 – February 14
- Q3: February 15 – May 14
- Q4: May 15 – August 14
