Sum Data From Multiple Sheets

I have workbook with 12 worksheets (sample show only Jan and Feb sheets) from which I want to summary data onto a single Summary (see tab on worksheet) sheet. Each worksheet has three sections: Income, Expense, and Spending. From each of these sections I want to summarize data from columns: Description, Amount and Date.

For example, from Income section of all worksheets, I want Excel to look at the Descriptions column and total the Amounts for all items with the same description, that fall between two dates. Then Excel look at Expense section Description column and total the Amounts for all items with the same description, that fall between two dates. Then do the same for the Spending section.

The descriptions who's Amounts to be totaled cannot pre-exist on the summary sheet, so I need Excel to fine each unique description, list it once on summary sheet, then calculate the total. I’ve attached a sample file. The SUMMAY EXAMPLE sheet is what I would like the result to look like on SUMMARY sheet, but I’m open to a different layout.
