The person that wrote the PHP Date function is a genious. I use it in almost every PHP application I write and its usage is so simple to work with. I have recently completed work on a booking calendar for www.tenerife-property-rentals.co.uk - which allows users to book any number of dates from an availability calendar. If it wasn’t for the mktime() and date(), it would have taken a long long time!

If anyone has an ASP alternative, please let me know.
