# Pledge Calculation

A list of the different frequencies during which gifts can be pledged.

## How are pledges calculated?

Once a week
This frequency calculates the pledge total based on the number of Sundays between the start date and stop date. So a range as short as eight days that includes two Sundays would be calculated as two pledges.
Every two weeks
This frequency calculates one pledge occurrence for every other Sunday, starting with the first Sunday in between the start date and stop date. So a range as short as fifteen days that begins on a Sunday would be calculated as two pledges.
Once a month
This frequency calculates a pledge for each month. So a range as short as two days—if it spans two months—would be calculated as two pledges.
Twice a month
This frequency calculates two pledges for each month. So a range as short as two days—if it spans two months—would be calculated as four pledges.
Quarterly
This frequency calculates a pledge for each quarter. So a range as short as two days—if it spans two quarters—would be calculated as two pledges.
Annually
This frequency calculates a pledge for each year. So a range as short as two days—if it spans two years—would be calculated as two pledges.
