Isaiah's Time Date Demo

The following are examples of getdate() AND strtotime()

String:

Time String:

Enter a string and that string will be evaluated via the getdate() and strtotime() functions.

For example, try strings like "tomorrow 1:30pm", or "Today", or "Yesterday", or "Next Month", or "+2 weeks monday", or "+2 mondays" and see what happens.

Also try your birthday, like John Lennon was born on October 9, 1940. What day of the week was that?
