Do a numerical calc _scheduled\_starttime_ - (1/24) 1 day in advance is -1 ---

Hi @elizabethteresa17, Just in case - Adalo can **not** send scheduled notifications by itself. You will need to use Zapier / Make / other service for that. Best, Victor. ---

Ah ok, now I remember this thread. Unfortunately I was not able to persuade you that if you close the app / all app instances, notifications won’t be sent. Adalo does not have any backend scheduler and **all** events are triggered by something which happens in the open app(s) on user(s) devices. In Adalo date & time is stored in number of days since 1/1/1970. If you would like to add one day (24 hours) to a certain datetime in a certain property, you need to add 1. If you would like to deduct a day, you need to deduct 1. So, if you would like to deduct one hour from a certain datetime , you need to deduct (1/24). If you need to add 2 hours, you need to add (2/24). ---

@elizabethteresa17, checkout scheduled notifications! > **[Scheduled Notifications | Adalo Resources](https://help.adalo.com/action-basics/notifications/scheduled-notifications)** > > Allow your app to send a push messages to users at a future date and time, even if the app is not open.
