# Timezone Reference
> Complete guide to IANA timezone identifiers for Cronhost schedules
# Timezone Reference
When creating schedules with Cronhost, you need to specify a timezone using IANA timezone identifiers. This ensures your scheduled HTTP requests run at the correct local time, regardless of where our servers are located.
## Overview
IANA (Internet Assigned Numbers Authority) timezone identifiers are standardized timezone names that handle daylight saving time transitions automatically. When you specify `"0 9 * * *"` (9 AM daily) with timezone `"America/New_York"`, Cronhost will:
* Run at 9 AM EST during winter months
* Run at 9 AM EDT during summer months
* Handle the DST transitions automatically
Always use IANA identifiers like `"America/New_York"` instead of abbreviations
like `"EST"` or `"PST"`. Abbreviations don't handle daylight saving time
correctly.
## Quick Examples
Here are some common timezone examples for creating Cronhost schedules:
```bash cURL theme={null}
curl -X POST "https://cronho.st/api/v1/schedules" \
-H "x-api-key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"name": "Daily Report",
"cronExpression": "0 9 * * *",
"timezone": "America/New_York",
"endpoint": "https://api.example.com/report"
}'
```
```typescript SDK theme={null}
const schedule = await cronhost.createSchedule({
name: "Daily Report",
cronExpression: "0 9 * * *",
timezone: "America/New_York", // Eastern Time
endpoint: "https://api.example.com/report",
httpMethod: "GET",
});
```
## Popular Timezones
Most commonly used timezone identifiers:
| Timezone | Identifier | Description |
| ------------------- | --------------------- | -------------------------- |
| 🇺🇸 Eastern Time | `America/New_York` | US East Coast (EST/EDT) |
| 🇺🇸 Central Time | `America/Chicago` | US Central (CST/CDT) |
| 🇺🇸 Mountain Time | `America/Denver` | US Mountain (MST/MDT) |
| 🇺🇸 Pacific Time | `America/Los_Angeles` | US West Coast (PST/PDT) |
| 🇬🇧 London | `Europe/London` | UK (GMT/BST) |
| 🇪🇺 Central Europe | `Europe/Berlin` | CET/CEST |
| 🇯🇵 Tokyo | `Asia/Tokyo` | Japan Standard Time |
| 🇦🇺 Sydney | `Australia/Sydney` | Australian Eastern Time |
| 🌍 UTC | `UTC` | Coordinated Universal Time |

### UTC
* `UTC` - Coordinated Universal Time
## Best Practices for Cronhost
1. **Always use IANA identifiers** - Never use abbreviations like "EST" or "PST"
2. **Test DST transitions** - Verify your schedules work correctly during spring/fall time changes
3. **Use UTC for global services** - If your API serves global users, consider UTC
4. **Be specific with locations** - Use `America/New_York` instead of generic `EST`
5. **Document your choice** - Include timezone reasoning in your schedule descriptions
## Schedule Examples by Region
### US Business Hours
```typescript theme={null}
// East Coast business hours (9 AM - 5 PM ET)
const eastCoastSchedule = await cronhost.createSchedule({
name: "East Coast Business Hours Check",
cronExpression: "0 9-17 * * 1-5", // Weekdays 9 AM - 5 PM
timezone: "America/New_York",
});
// West Coast business hours (9 AM - 5 PM PT)
const westCoastSchedule = await cronhost.createSchedule({
name: "West Coast Business Hours Check",
cronExpression: "0 9-17 * * 1-5", // Weekdays 9 AM - 5 PM
timezone: "America/Los_Angeles",
});
```
### Global Monitoring
```typescript theme={null}
// Global service monitoring every hour
const globalMonitoring = await cronhost.createSchedule({
name: "Global API Health Check",
cronExpression: "0 * * * *", // Every hour
timezone: "UTC", // Consistent global timing
});
```
### European Operations
```typescript theme={null}
// European business hours monitoring
const europeanSchedule = await cronhost.createSchedule({
name: "European Business Hours",
cronExpression: "0 8-18 * * 1-5", // Weekdays 8 AM - 6 PM
timezone: "Europe/London", // Handles GMT/BST automatically
});
```
## Common Gotchas
**Daylight Saving Time**: When DST transitions occur, some times may be skipped (spring forward) or occur twice (fall back). Cronhost handles this automatically, but be aware:
**Spring Forward**: 2:30 AM might be skipped entirely
**Fall Back**: 2:30 AM might run twice
**Arizona Exception**: Most of Arizona doesn't observe DST. Use
`America/Phoenix` for consistent Mountain Standard Time year-round.
