A sericulture calendar that shows only the next step

Silkworm Batch Calendar

Enter a start date and a batch type, and the tool shows just the next action.

Inputs stay in this browser by default. Nothing is sent to a server.

What this tool does

Show only the next action

Track the flow from egg placement to dried cocoon, but display only the one next step you need now.

Use today or a fixed date

Check the batch in the present, or pin the reference date to reproduce a past day exactly.

Share the same condition by URL

Put the start date, type, and reference-date mode into the URL so the same screen can be reopened later.

Keep storage in the browser

Local storage is the default. You only need the share URL when moving between devices.

How to use

  1. Enter the batch start date.
  2. Choose a batch type, which acts as the schedule template.
  3. Choose today or a fixed date as the reference date.
  4. Read the next action and copy or share it if needed.

Longer batches still stay simple: just the next milestone appears.

FAQ

What does the batch type mean?

It chooses the schedule template for the region or operation. It is not the silkworm strain itself.

Why not show the full schedule?

The point of this tool is to answer the question, 'What is next?' without a long table getting in the way.

Can I use a past batch?

Yes. Pin the reference date to a fixed day and the tool will recalculate from that point in time.

What if my region uses different timings?

Keep the labels and adjust the offsets in the template constants to match local guidance.

Glossary

Egg placement

The step that starts the batch from silkworm eggs.

Hatching

The larvae emerge from the eggs.

Larval transfer

The hatched larvae are moved onto the rearing bed and the work begins.

Molt

The resting stage before and after a skin change. The tool tracks four molts.

Feeding

Mulberry leaves are fed during each larval stage.

Mounting

Mature larvae are moved to mounts so they can spin cocoons.

Cocoon harvest

Completed cocoons are collected.

Cocoon drying

The cocoons are dried for storage or shipment.

Notes

  • Timing changes with region, strain, and temperature management.
  • Use this tool to confirm the next step only, then follow your local sericulture guide.
  • When you need to reproduce a past batch or share it, pin the reference date.
