## enable_extended_results_for_datetime_functions {#enable-extended-results-for-datetime-functions}
Enables or disables returning results of type `Date32` with extended range (compared to type `Date`) for functions [toStartOfYear](../../sql-reference/functions/date-time-functions.md#tostartofyear), [toStartOfISOYear](../../sql-reference/functions/date-time-functions.md#tostartofisoyear), [toStartOfQuarter](../../sql-reference/functions/date-time-functions.md#tostartofquarter), [toStartOfMonth](../../sql-reference/functions/date-time-functions.md#tostartofmonth), [toStartOfWeek](../../sql-reference/functions/date-time-functions.md#tostartofweek), [toMonday](../../sql-reference/functions/date-time-functions.md#tomonday) and [toLastDayOfMonth](../../sql-reference/functions/date-time-functions.md#tolastdayofmonth).
Possible values:
- 0 — Functions return `Date` for all types of arguments.
- 1 — Functions return `Date32` for `Date32` or `DateTime64` arguments and `Date` otherwise.
Default value: `0`.
## optimize_move_to_prewhere {#optimize_move_to_prewhere}

The return type of `toStartOf*`, `toLastDayOfMonth`, `toMonday` functions described below is `Date` or `DateTime`.
Though these functions can take values of the extended types `Date32` and `DateTime64` as an argument, passing them a time outside the normal range (year 1970 to 2149 for `Date` / 2106 for `DateTime`) will produce wrong results.
In case argument is out of normal range:
The return type of `toStartOf*`, `toLastDayOfMonth`, `toMonday` functions described below is determined by the configuration parameter [enable_extended_results_for_datetime_functions](../../operations/settings/settings#enable-extended-results-for-datetime-functions) which is `0` by default.
Behavior for
* `enable_extended_results_for_datetime_functions = 0`: Functions `toStartOf*`, `toLastDayOfMonth`, `toMonday` return `Date` or `DateTime`. Though these functions can take values of the extended types `Date32` and `DateTime64` as an argument, passing them a time outside the normal range (year 1970 to 2149 for `Date` / 2106 for `DateTime`) will produce wrong results. In case argument is out of normal range:
* If the argument is smaller than 1970, the result will be calculated from the argument `1970-01-01 (00:00:00)` instead.
* If the return type is `DateTime` and the argument is larger than `2106-02-07 08:28:15`, the result will be calculated from the argument `2106-02-07 08:28:15` instead.
* If the return type is `Date` and the argument is larger than `2149-06-06`, the result will be calculated from the argument `2149-06-06` instead.
* If `toLastDayOfMonth` is called with an argument greater then `2149-05-31`, the result will be calculated from the argument `2149-05-31` instead.
* `enable_extended_results_for_datetime_functions = 1`: Functions `toStartOfYear`, `toStartOfISOYear`, `toStartOfQuarter`, `toStartOfMonth`, `toStartOfWeek`, `toLastDayOfMonth`, `toMonday` return `Date` or `DateTime` if their argument is a `Date` or `DateTime`, and they return `Date32` or `DateTime64` if their argument is a `Date32` or `DateTime64`.

Данная функция может использоваться, например, для анализа количества просмотров страницы за соответствующую сессию.
Аргумент `StartTime` может иметь тип `DateTime` или `DateTime64`. В случае, если используется `DateTime`, аргументы `Duration` и `Size` должны иметь тип `UInt32`; Для DateTime64 они должны быть типа `Decimal64`.
Аргумент `StartTime` может иметь тип `DateTime` или `DateTime64`. В случае, если используется `DateTime`, аргументы `Duration` и `Size` должны иметь тип `UInt32`; Для DateTime64 они должны быть типа `Decimal64`.
Возвращает массив DateTime/DateTime64 (тип будет совпадать с типом параметра ’StartTime’). Для DateTime64 масштаб(scale) возвращаемой величины может отличаться от масштаба фргумента ’StartTime’ --- результат будет иметь наибольший масштаб среди всех данных аргументов.
