Build a useful season record
Start with the tag or name you already use in your farm records. Give each animal a separate entry when the breeding date is known. For a pasture-exposed group, use a clear group name and keep both the first and last days with the male. A group entry represents an exposure record; it does not count or confirm pregnancies within that group.
Choose the species and the closest available breed, then check the dates before adding the record. The list recalculates its estimates from the same reference values used by the calculators. Keep the original breeding notes as well, especially when the entry is based on turnout rather than an observed service. An estimated due date should never replace the record that produced it.
Read the list and calendar together
The list helps you compare tags, breeding dates, due dates, windows, and status. Sorting by due date brings the expected start of the season into view; sorting by animal helps review species or breed groups. An average due date and the full window answer different questions, so use both when organizing calving, kidding, or lambing preparations.
Switch to Calendar to group the entries by their first expected due month. A pasture-bred entry stays a range even when its window continues into another month. Print the calendar for the barn wall, and check the printed date before replacing an older copy. Printing or changing views does not turn an exposure estimate into a confirmed conception date.
Keep a copy beyond this browser
The planner saves the list locally in this browser on this device. It does not synchronize between phones and computers. Export a CSV for a backup or to move the records, and review import messages so skipped rows do not go unnoticed. Notes travel with CSV exports; compact share links carry the breeding entries without notes.
A share link puts the list after the hash mark in the URL. Browsers do not send that fragment to our server, but anyone receiving the link can read its entries. Share only the information you intend to share. A recipient can view the list or choose to add or replace their local list; opening a link does not silently overwrite saved records.
Keep actual birth dates and veterinary confirmation in your farm records alongside these estimates. The breeding guides and source tables explain the averages and windows. For pregnancy confirmation or a concern about an animal, call your veterinarian.
