Field layout and time zones
second (0-59), minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
node-cron uses the server time zone unless you pass { timezone: "Asia/Kolkata" }. Its documentation advises timezone: "UTC" for jobs that must not skip or repeat when clocks change.
second (0-59), minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Spring evaluates in the server time zone by default. Add zone = "UTC" (or any ZoneId) to @Scheduled to make it explicit.

Frequently asked questions
How do I convert a node-cron cron expression to Spring?
Paste it into the converter above with node-cron as the source and Spring as the target. For example, * * * * * becomes 0 * * * * *.
Is every node-cron expression convertible to Spring?
Yes for the common schedules we tested (32 of 32), though unusual expressions with special characters might need manual review.
Does Spring run in the same time zone as node-cron?
Not necessarily. Conversion changes the syntax, not the time zone. Check where each system evaluates the schedule before you rely on the same clock times.
