Date to Unix Timestamp (Epoch) Converter
Convert human-readable dates and times to Unix timestamps (seconds since epoch) for local time or UTC.
What is a Date to Unix Timestamp Converter?
A Date to Unix Timestamp Converter transforms human-readable dates and times into Unix timestamps (also known as Epoch time). A Unix timestamp represents the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. This conversion is crucial for developers needing to store dates in database systems, work with APIs that require timestamp formats, or when programming time-based functions in various applications. For reference, the current Unix epoch time is constantly increasing.
Features of Our Date to Unix Converter
Our date to Unix timestamp conversion tool provides these specific capabilities:
- Convert any date and time to Unix timestamp format
- User-friendly date and time selection interface
- Support for local and UTC timezone conversion
- Precisely calculated timestamp results
- Copy-to-clipboard functionality for convenient use
How to Use the Date to Unix Converter
- Select your Date using the date picker interface
- Enter the Time using the time input field (e.g., 14:30 for 2:30 PM)
- Select the timezone for the input date and time:
- Local Time: Assumes the entered date/time is in your browser's local timezone.
- UTC: Assumes the entered date/time is in Coordinated Universal Time.
- Click the "Convert to Unix" button
- View the resulting Unix timestamp (in seconds). The corresponding GMT/UTC time of the input is also shown for clarity.
- Use the copy button to copy the timestamp to your clipboard if needed
The result will show the Unix timestamp in seconds. The conversion to timestamp is always based on the UTC equivalent of the input date and time, according to your timezone selection.
What is Epoch Time?
The Unix epoch (or Unix time, POSIX time, Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z). Literally speaking, the epoch is Unix time 0 (midnight 1/1/1970), but 'epoch' is often used as a synonym for Unix time. Some systems store epoch dates as a signed 32-bit integer, which might cause problems on January 19, 2038 (known as the Year 2038 problem or Y2K38).
Common time units in seconds:
Human-readable time | Seconds |
---|---|
1 hour | 3600 seconds |
1 day | 86400 seconds |
1 week | 604800 seconds |
1 month (30.44 days) | 2629743 seconds |
1 year (365.24 days) | 31556926 seconds |
How to Get the Current Epoch Time in Various Languages
Here are some examples of how to get the current Unix epoch time (seconds since epoch) in different programming languages:
PHP
time();
Python
import time;
time.time()
Ruby
Time.now.to_i
Perl
time
Java
long epoch = System.currentTimeMillis()/1000;
C#
DateTimeOffset.Now.ToUnixTimeSeconds();
JavaScript
Math.floor(Date.now() / 1000);
Go
import "time"
func main() {
fmt.Println(time.Now().Unix())
}
Swift
NSDate().timeIntervalSince1970
MySQL
SELECT unix_timestamp(now());
PostgreSQL
SELECT extract(epoch from now());
SQLite
SELECT strftime('%s', 'now');
Date to Unix Conversion FAQs
Why would I convert a date to a Unix timestamp?
Unix timestamps are useful for storing dates in databases, working with APIs, performing date calculations, or when developing applications. They offer a standardized, timezone-independent way to represent points in time as simple integers, making them convenient for storage and calculation purposes.
How do timezones affect Unix timestamps?
Unix timestamps are always in UTC (Coordinated Universal Time). When converting a date to a Unix timestamp, our tool allows you to specify if the input date/time is in your "Local Time" or "UTC". If "Local Time" is selected, the tool first converts your local time to its UTC equivalent, and then calculates the timestamp. If "UTC" is selected, it assumes the input is already in UTC.
What's the difference between seconds and milliseconds in Unix time?
Standard Unix timestamps count seconds since the epoch. However, some systems (like JavaScript's Date.now()) use milliseconds instead. Our converter generates the standard seconds-based timestamp. If you need milliseconds, simply multiply the result by 1000.
