└─────────────────────┴────────────────────────────────────────────────────────────┘
|

```
|
||||
|
||||
You can set the period without using `INTERVAL` by multiplying seconds, minutes, and hours. For example, a period of one day can be set at `60*60*24`.
|
||||
|
||||
!!! note "Note"
|
||||
Syntax `now() + 60*60*24` doesn't consider time settings. For example, daylight saving time.
|
||||
|
||||
The `INTERVAL` syntax or `addDays`-function is always preferred.
|
||||
|
||||
Examples:
|
||||
|
||||
``` sql
|
||||
SELECT now() AS current_date_time, current_date_time + 60*60*96;
|
||||
```
|
||||
|
||||
