Sometimes Salesforce admin/user needs to know which custom fields created in a certain time frame like THIS Week/Month/Year, etc.
We can use Salesforce Tooling API to get the Custom Field information. We can query the Custom Field metadata information inside Salesforce developer console, you just need to check the “Use Tooling API” checkbox. Below is the screenshot showing the lists of custom fields created this year.
Query: SELECT DeveloperName,CreatedDate,TableEnumOrId FROM CustomField where CreatedDate = THIS_YEAR
