There are a lot of endpoints that allow you to filter on a date such as the date that a record was inserted or updated. In these cases you can filter based on a range of values.
The most simple filter is just specifying a date and checking for equality. When you specify a date use the RFC339 format. Here are some examples:
This is a flexible, unambiguous format that allows you to specify a date, date/time, and also specify timezones.
Basic Date Operations
Usually, you don’t want to filter on an exact date, but rather specify an operation. To do this put one of the
=,>,<,>=,<= operations before the date.
You can also filter based on date ranges. To do this you put two dates between brackets, seperated by a comma. You can use square brackets
 for inclusive ranges and round brackets
() fore exclusive ranges. You can also mix and match brackets.
[2018-01-01,2019-01-01) // anything in 2019
Date Filters Must Be Encoded
Most date filters are supplied in the query string which means they have to be encoded just like any other query string parameter. Most dates will work regardless of encoding, but it is considered a best practice to always encode.
