As local school officials have pointed out quite a few times this winter, it's tough to predict how many snow days a district will need.

One year, York County residents might see nothing more than a dusting; other years well, they can see for themselves.

This winter has been brutal and relentless.

Some districts already have plowed through their anticipated, built-in snow days and are adding dates to meet the state's required 180-day school calendar — unless, of course, they don't mind losing their state education subsidies.

Surprisingly, that option is on the table in the Central York School District.

As of Wednesday, the district has canceled classes seven days this school year. That means based on the current school calendar seniors will go attend classes for only 179 days, one shy of state law.

That's if there are no more snow days, and we have a pretty good hunch that's not going to be the case.

Superintendent Michael Snell recently gave the school board options to deal with the seniors' missing days: Move the graduation, now set for May 30; have seniors attend school on Saturdays; designate more snow make-up days; or change two teacher in-service days to classroom days.

The fifth choice is to forgo the state funding, which would amount to $3,000 a day for every day seniors are under the 180-day requirement.

The board has decided to wait until after this week's anticipated snow fall to make a decision, but one member made clear she won't saddle taxpayers with $3,000 a day in lost revenue just so seniors can graduate on time.

While moving the graduation date at this point might inconvenience students and their families, we agree with board member Deborah Myers — if it's a choice between that and losing state funding, everyone will just have to change their plans.

The board might be able to avoid a similar situation in the future by following another member's advice.

Board member Eric Wolfgang said when he first started on the board, the calendar did not include a set graduation date. He said he'd rather wait to set that date until next February or March.

Considering how fickle Mother Nature has been in recent years, that's probably not a bad idea.
