## What is Date Batch Calculator?

Still checking “how many days since this date?” one entry at a time?

Date Batch Calculator saves multiple starting dates and compares all of them with today or a reference date you choose. See elapsed days and days remaining together in one clear list.

Paste multiple lines to add dates in a batch, or use the built-in calculator for date differences and dates a certain number of days before or after another date.

Features:
• Save and label multiple dates
• Recalculate the full list using today automatically
• Switch every result to a custom reference date
• Preview and import multiple pasted dates
• Calculate days between two dates
• Calculate a date before or after another date
• Choose standard or inclusive counting
• Sort saved dates
• Export CSV with Pro
• Keep saved date records on your device

Pro is a one-time purchase, not a subscription.

This is a general-purpose date calculator. It does not provide or guarantee legal, medical, government, or other official deadline advice.
