1. Calculate N days before / after a fixed date
Choose a date and enter N days from 0 to 1000. Select before, after, or both.
Example: fixed date 2026-06-03, N = 30. After: 2026-07-03; before: 2026-05-04.
2. Calculate days between two dates
Choose date A and date B. The result is B - A, so it can be negative.
Example: 2026-01-01 to 2026-02-01 is 31 days; reversed is -31 days.
3. Calculate the interval between two times
The input format changes with the selected unit. The result is B - A, so negative intervals are allowed.
Example: choose hours, A = 2025/01/01 00, B = 2025/01/02 12, result = 36 hours.
4. Calculate before / after by period and parameters
Set a fixed time, parameter A from 0 to 1000, and unit B: seconds, minutes, hours, days, weeks, months, or quarters.
Example: fixed time 2026-06-03 12:00:00, A = 2, B = weeks. Before: 2026-05-20 12:00:00; after: 2026-06-17 12:00:00.
5. Time / timestamp conversion
Convert 5 times to timestamps and 5 timestamps back to times at once. Times use the local timezone; timestamps can be seconds or milliseconds.
Example: convert 2026-06-03 12:00:00 to a Unix timestamp, or enter a timestamp to get local time.
6. K-line bar count calculator
Enter time A and B, choose a candlestick period, and calculate how many complete bars are between B - A. If A is later than B, the result is negative.
Example: A = 2026-06-01 00:00:00, B = 2026-06-02 00:00:00, period = 1 hour, result = 24 bars.
