Not sure where y'all are located, but I'd suggest calving during your peak grass growing season. We just had an accidental calf during the middle of winter and got very lucky that it wasn't extremely cold out like last week. A dead calf would be a huge setback for small scale beef production.

Taking responsibility from "sperm to spork" is very rewarding but a very long term game--~39 months until you get beef. Potentially having to wait a few months to align for your optimal season will pay dividends for years to come.

My 2 sats about halfway through our beef flywheel spinning up.
