Overview
Unix Timestamp Converter works by converting Unix epoch timestamps to formatted dates or parsing date strings into Unix timestamps. Returns comprehensive date information including year, month, day, time components, and multiple standard formats.
Endpoint
One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.
curl "https://api.apiverve.com/v1/unixtimestamp?timestamp=1609459200&format=seconds" \
-H "x-api-key: your_api_key_here"const res = await fetch('https://api.apiverve.com/v1/unixtimestamp?timestamp=1609459200&format=seconds', {
headers: { 'x-api-key': 'your_api_key_here' },
});
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
const { data } = await res.json();
console.log(data);import requests
res = requests.get(
"https://api.apiverve.com/v1/unixtimestamp?timestamp=1609459200&format=seconds",
headers={"x-api-key": "your_api_key_here"},
timeout=15,
)
res.raise_for_status()
print(res.json()["data"])package main
import (
"fmt"
"io"
"net/http"
)
func main() {
req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/unixtimestamp?timestamp=1609459200&format=seconds", nil)
req.Header.Set("x-api-key", "your_api_key_here")
res, err := http.DefaultClient.Do(req)
if err != nil {
panic(err)
}
defer res.Body.Close()
out, _ := io.ReadAll(res.Body)
fmt.Println(string(out))
}Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.
Authentication
Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.
A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.
Parameters
Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.
| Parameter | Type | Description |
|---|---|---|
timestampRequired | string | Unix timestamp to convert timestamp |
formatOptional | string | Timestamp formatsecondsmillisecondssmsdefault seconds |
Response
Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

}Response fields
Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.
| Field | Type | Example | Description |
|---|---|---|---|
timestamp | number | 1609459200 | Unix timestamp in requested format |
timestamp_format | string | "seconds" | Format of the timestamp value returned |
iso_8601 | string | "2021-01-01T00:00:00Z" | Date formatted in ISO 8601 standard |
rfc_2822 | string | "Fri, 01 Jan 2021 00:00:00 GMT" | Date formatted in RFC 2822 standard |
date | string | "1/1/2021" | Date in simple M/D/YYYY format |
time | string | "12:00:00 AM" | Time in HH:MM:SS AM/PM format |
unix_seconds | number | 1609459200 | Unix timestamp in seconds |
unix_millisecondsPremium | number | 1609459200000 | Unix timestamp in milliseconds |
year | number | 2021 | Year component extracted from timestamp |
month | number | 1 | Month component from 1 to 12 |
day | number | 1 | Day of month component |
hour | number | 0 | Hour component in 24-hour format |
minute | number | 0 | Minute component of the time |
second | number | 0 | Second component of the time |
day_of_weekPremium | string | "Friday" | Full name of the day of week |
timezone | string | "UTC" | Timezone of the returned date |
Errors
Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.
| Status | Meaning | What to do |
|---|---|---|
400 | Input was rejected | Read error; it names the parameter. |
401 | Key missing or invalid | Check the header name and the key value. |
403 | Key valid, but not permitted | A key restriction or IP allow-list; see key scoping. |
429 | Rate limited, or out of credits | Read error to tell them apart; see rate limits. |
Use cases
- API Development
- Convert timestamps from databases and APIs to human-readable dates for display in applications
- Log Analysis
- Parse timestamps in log files and system events for debugging and monitoring
- Data Migration
- Convert date formats between different systems and databases during data transfer
- Time Synchronization
- Standardize time representations across distributed systems using epoch timestamps
Other ways to use Unix Timestamp Converter
Set up Unix Timestamp Converter on APIVerve, or reach the same source a different way. Your APIVerve account and credits work on all of them — one key, one balance.
