With the daily reports we're tracking real calendar days, so you end up choosing a real calendar month when you choose an entire month. For example, April 1st to April 30th includes all of those days.

In the financial reports we're using a fiscal calendar that matches Apple's fiscal calendar, so this may cut off the first few days, or the last few days of a month.

The fiscal calendar’s pattern is simple and follows several basic rules:

1. Every month starts on a Sunday and ends on a Saturday.

2. Q1 starts at the end of September

3. Every quarter starts with a 5-week month, followed by two 4-weeks months
