Comprehensive breakdown of the 23-hour period and other time references.
Need to find what time it was 23 hours ago?
Here are several ways to calculate it in different programming languages:
// PHP
// Get time from 23 hours ago
$pastDate = date('Y-m-d H:i:s', strtotime('-23 hours'));
// Get time 23 hours from now
$futureDate = date('Y-m-d H:i:s', strtotime('+23 hours'));
// Using DateTime (recommended approach)
$date = new DateTime();
$date->modify('-23 hours');
echo $date->format('Y-m-d H:i:s');
// JavaScript // Get time from 23 hours ago const pastDate = new Date(Date.now() - 23 * 60 * 60 * 1000); // Get time 23 hours from now const futureDate = new Date(Date.now() + 23 * 60 * 60 * 1000); // Alternative approach using date methods const date = new Date(); date.setHours(date.getHours() - 23); console.log(date.toISOString());
# Python
from datetime import datetime, timedelta
# Get time from 23 hours ago
past_date = datetime.now() - timedelta(hours=23)
# Get time 23 hours from now
future_date = datetime.now() + timedelta(hours=23)
# Format the dates
print(past_date.strftime('%Y-%m-%d %H:%M:%S'))
print(future_date.strftime('%Y-%m-%d %H:%M:%S'))
