This is a draft PR for beginning work on BigQuery DATE_ADD() and DATE_DIFF() functions. DATE_ADD() is currently functioning as expected. DATE_DIFF() is facing a small issue where 'week' is not working as expected because BigQuery considers a 'week' beginning on Sunday (so the difference between dates on a Saturday and Sunday would return 1 despite only being a day apart). If anyone has any comments about this issue or any other changes I would highly appreciate it! More info about these functions is below. DATE_ADD(date_expression, interval) adds the interval to the date expression. Example: DATE_ADD(DATE '2008-12-25', INTERVAL 3 DAY) would return '2008-12-28'. BigQuery docs: https://cloud.google.com/bigquery/docs/reference/standard-sql/date_functions#date_add DATE_DIFF(date_expression, date_expression2, time_unit) returns the whole number of time_unit between the first and second date expressions, with the result being negative if the first date is earlier than the second. Example: DATE_DIFF(DATE '2008-12-25', DATE '2008-12-28', DAY) would return -3.
