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).
Spring evaluates in the server time zone by default. Add zone = "UTC" (or any ZoneId) to @Scheduled to make it explicit.
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.

Frequently asked questions
How do I convert a Spring cron expression to node-cron?
Paste it into the converter above with Spring as the source and node-cron as the target. For example, 0 * * * * * becomes * * * * *.
Is every Spring expression convertible to node-cron?
Yes for the common schedules we tested (32 of 32), though unusual expressions with special characters might need manual review.
Does node-cron run in the same time zone as Spring?
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.
