- [How does Cronofy handle Daylight Saving Time?](/developers/faqs/event-management/daylight-saving/index.md) — When Daylight Saving Time starts, all end user calendars that exist within timezones with Daylight Saving Time will be moved to a new timezone based on their calendar integration.
- [Why aren’t my events appearing when I read a user’s events?](/developers/faqs/event-management/events-not-appearing/index.md) — By default we don’t return events your application has created when you query the Read Events endpoint.
- [Why do I get duplicate events?](/developers/faqs/event-management/duplicate-events/index.md) — If you're getting duplicated events when you edit existing events, it may be because of how you're using event_id and event_uid values.
- [What would be the recommended way to sync all events inside an end users calendar with my application?](/developers/faqs/event-management/recommended-sync/index.md) — A guide explaining how to properly sync events and the best ways to keep users calendar's up to date with your application
- [Will I receive notifications for events that are newly created?](/developers/faqs/event-management/event-notifications/index.md) — Assuming you are subscribed to all events, including external, you will receive notifications about newly created events.
- [Why doesn't Cronofy issue event ids?](/developers/faqs/event-management/event-ids/index.md) — We don’t issue IDs to events, instead we require that developers provide an event_idwhen upserting an event to a user’s calendar. This is then used to identify the event when making subsquent updates/deletes.
- [What is the difference between event_id and event_uid?](/developers/faqs/event-management/event-id-event-uid/index.md) — The event_id is only used for events that your application creates, what we call *managed* events. This is an ID that your application specifies. We use it as a key for an application's managed events.
- [Why can't I avoid notifying attendees when updating an event?](/developers/faqs/event-management/avoid-notifying-attendees/index.md) — While some calendar providers allow you to suppress notifications being sent to attendees when an event is changed, not all do.
- [How can I create an event without the participants seeing each other's details?](/developers/faqs/event-management/hide-attendees-list/index.md) — By creating a main event in the host's calendar and inviting the attendees via Smart Invites, you can ensure participants cannot see each other's details.
- [Why do events in secondary Google calendars appear in my primary calendar too?](/developers/faqs/event-management/google-secondary-calendars/index.md) — Due to the original implementation of Google Calendars, and to provide consistency with Microsoft calendar behaviour, Cronofy adds the primary calendar as the event Organizer.
