I personally wouldn't have a problem with it, but use a hyphen ( - ) to mean 'to', not a tilde ( ~ ).No.
It's more like self-imposed pressing needs.
I was writing an employment reference letter and wondering if there was a proper way to write periods without including date since there is no need to be that specific?
For example, I want to write something like "Dec. 2010 ~ Jun. 2011" but is it acceptable?
Nor am I, but when I was in med. school, all our professors used it for non-mathematical shorthand to mean "about".Good point. I expect this is something to do with the mathematical symbol for 'is approximately equal to': ≈ (I think, but I'm not a mathematician).

Yes, this is the difference. "~" means approximately. "≈" means is approximately equal.Nor am I, but when I was in med. school, all our professors used it for non-mathematical shorthand to mean "about".
"PR ~ 72" (Pulse rate around 72 beats/min), etc.
"Laceration on L arm ~ 3cm long."
(I don't count guessing approximate measurements as mathematics.)
Yes, this is the difference. "~" means approximately. "≈" means is approximately equal.
