Calculate Timestamp and Date

The Unix timestamp counts the milliseconds since January 1. 1970 UTC (Coordinated Universal Time). Often computer programs use this value, when calculations with time and date have to be made. Here, the current timestamp can be shown, the timestamp of any date can be calculated and any timestamp can be converted to a date. Current time and date are displayed as local time.

Example: The last millennium actually began on January 1, 2001. However, the date is usually given as one year earlier, i.e., the transition from 1999 to 2000. The timestamp for the first date is 946681200000, and for the second date, it is 978303600000.

Current timestamp enters the timestamp of the time which is running now on your system.
Timestamp to date ↓ converts a timestamp to date and time.
Date to timestamp ↑ of course converts date and time to a timestamp.

A timestamp refers to the exact time of a specific date. Originally, and still today, a physical stamp was used for this purpose. This is a device in which the time and/or date are printed raised in mirror writing on a surface. It is first pressed in ink and then pressed onto paper or something similar, thus leaving the time legible. This is familiar from the postal service, which marks letters and parcels in this way. Timestamps can also be implemented digitally; even in digital form, they can display the time and date in the usual, easily legible format. The Unix timestamp, on the other hand, is a format that is barely readable by humans, but is extremely useful and widely used for precise computer calculations. A problem with this may arise starting January 19, 2038, on systems that work with signed 32-bit numbers, which could then result in an arithmetic overflow.
