How accurate is a lambing calendar?

It is very accurate for predicting the main drop, but individual ewes may vary by a few days.

Why do I need to know the breeding end date?

Knowing the end date tells you exactly when you can stop checking for new lambs and close out the season.

If rams run year-round, you cannot use a calendar. You will have to rely on visual signs of pregnancy.

Many shepherds shear 4-6 weeks before the calculated lambing start date.
