Wolfram Alpha tells me that 7 years is equal to 84 months, 365 weeks, 2555 days, 61320 hours, 6.995025 anomalistic years, or 6.99508694957 sidereal years.
In other '7 year' news, The Eiffel Tower is painted approximately once every 7 years and requires nearly 50 tons of paint each time according to this site. And it appears to be a myth that in the length of time this blog has existed, I have replaced every cell in my body.
Happy birthday, hippie blog!
