# How to mark your calendar?
> Mark your calendar accordingly to ensure your out of office and internal slots are read correctly by RevenueHero.
## Marking Out of Office/Vacations
Nobody likes to be bothered with meetings when you're out of office.
Let's mark your calendar accordingly so that RevenueHero can prevent prospects from booking on those times.
### Google Calendar
1. Click on the top-bar right below the date.
2. Click on **Out of Office** and select the dates that your on vacation for.
### Outlook Calendar
1. Click on the top-bar right below the date.
2. Click on **Out of Office** and select the dates that your on vacation for.
## Dealing with internal meetings/blocks
RevenueHero considers a slot as available on your calendar if you are free for the pre-meeting buffer, meeting duration and post-meeting buffer.
If the meeting buffers overlap with existing meetings, RevenueHero will not consider it as an available slot.
This allows some breathing space for you before/after your meeting and ensures that you will never again have a back-to-back meeting scheduler.
While you may have available slots for the meeting duration, your internal blocks/events might overlap with the pre/post meeting buffers.
To make more slots available for your prospects to book from, you can mark some of your internal slots as Free.
Here's how to do that on:
### Google Calendar
1. Click on the internal event/block that you want to mark as free and edit it.
2. Change the event from **Busy** to **Free**
### Outlook Calendar
1. Click on the internal event/block that you want to mark as free and edit it.
2. Change the event from **Busy** to **Free**
