How is availability calculated in the calendar?
1: In October 2022, Altru released in this article about a new feature that can be used to query remaining capacity for programs. Feel free to use this field to query the remaining capacity.

You may still refer to the old process of calculating the program availability below.
Calculating the availability in the calendar
Make sure that you already have the Calendar Query which is the output of all program information. This query gives the number of capacity you have set for a specific event.

2: We also need the Reserved Event Query to calculate the number of tickets sold. The query includes tickets that are sold and not refunded. Under this query, we’re outputting quantity.

3: Grab the capacity that was set based on the result of the calendar query less the number of tickets sold and the difference is the availability. This gives us the formula:
Calculating Sold
Use the formula above to calculate the availability but before you do that, determine first the number of tickets sold. We will base the total number of tickets sold on the output given by the reserved event query. The query will display the sales order with the total quantity of tickets for a particular event. You can calculate the number of items sold by taking the sum of all quantities in the output query.
By taking the capacity based on the Calendar Query and the quantity calculated by taking the sum of all quantities displayed on the sales order provided by the reserved event query, you can now calculate the number of availability for a calendar.
Frequently Asked Questions:
- What are the reasons for an incorrect quantity displayed on the calendar?
- The probable reason for an incorrect quantity displayed is refunds, partial refunds, cancellations, rescheduling, and so on. Because of that, you need to explicitly exclude refunds in your query.
- Include “Refund status is equal to 0” in your query to acquire data on tickets not refunded.
- You can also remove the ‘refund status is equal to 0’ if you wish to include a refund on the calculation for sold.
- To troubleshoot this issue, you need to output the specific date with a specific time for both queries. After that, you can now calculate the availability.

2. Can I manually override availability and mark it as sold out?
- Yes, you just need to go to your program and set the capacity to zero (0) and that will automatically pull the items off for you.
- To remove those partially refunded tickets from your calendar, just go to that particular event date and time and set the capacity to zero.
