strftime cheatsheet

I know there are other cheatsheets out there but I want one that’s close to home. I find myself needing to look up strftime parameters quite often in my Rails development work. Particularly difficult is remembering the different forms for the same time item. Anyway, here is a list formatted for my usage.

Names

• month name - %b (Abbr), %B (Full)
• day of week name - %a (Abbr), %A (Full)
• timezone - %Z (Name), %z (UTC offset)

Dates

• year - %y (2-digit), %Y (4-digit)
• month - %m (leading zero)
• day - %d (leading zero), %e (leading space)
• hour (24-hour) - %H (leading zero), %k (leading space)
• hour (12-hour) - %I (leading zero), %l (leading space)
• am/pm - %p (Uppercase), %P (lowercase)
• minute - %M (leading zero)
• second - %S (leading zero)
